Quadratic equations in real life : Class 10

Why study Quadratic Equations? Quadratic equations are used in numerous real-world applications. Parabola is the graphical representation of Quadratic Equations.

I’ve watched about 30 videos and this is the most helpful video out there even if I had a hard time understanding so thank you for the help

The Quadratic Equation never once made sense to me school. Simply by explaining the real-life applications of it, You helped me understand it. The application is very important to my brain's understanding of math.

It all went over my head in school, because my teacher never once gave a real-life example of this. Thank you

Linear equations in 2 variables me ek question aata hai, "Represent x = 1, on graph, w.r.t. single variable x." To usme, kewal x-axis banate hain, aur usme, equal intervals pe 0, 1, 2, 3, ... show karte hain. Aur 1 wale point ko bold karke, wahaan likh dete hain, x=1.

Ab yehi question, aise aata hai, "Represent x = 1 on the graph, w.r.t. 2 variables, x and y. Wahaan pe, is eqn ko fir se process karte hain, 1.x + 0.y = 1. Fir table banate hain aur usme for different values of y, we find different values of x. Aur unhe graph pe plot karte hain, to, we get a straight line parallel to the y-axis.

Ab isi logic ko, Quaadratic Polynomial pe lagao.

Ek question hai, represent y = 0 and y = x^2 + 3x + 2, curves on graph. To isme, pehle x-y plane draw karenge. Fir uspe y = 0 curve show karenge, yaani x-axis ko bold kar denge. Fir, y = x^2 + 3x + 2 parabola draw karenge. Fir, is graph pe, y = 0 curve aur y = x^2 + 3x + 2 ke points of intersection show kar denge. To ye complete graph, is question ka solution hoga.

Lekin agar yehi question aise hota hai, represent x^2 + 3x + 2 = 0, on the graph. To, isme, equation ke roots nikalenge (i.e., x = -1, -2), aur kewal roots ko x-axis pe represent kar denge.

Because this equation is equivalent to this question, "Represent x = 1, on graph, w.r.t. single variable x."

This one is really awesome, Can you please give some more detailed explanation of using quadratic equations in real life.

[manivannans]

Can we use this equation for eccentric reducer developement

[paanazmi]

The question, do engineers, technician architec really use quadratic equation to solve this problem?do these peopl actually take out the quadratic equation formula n calculate beforehand? Or they simply just use software to do calculation?

I have watched I think more than 30 this one is very useful video...thank you soo much sir... please continue this session...sir

[bigflat]

Don’t understand when getting taught this stuff that there is no real life examples(maybe I was sleeping )

[mathskefundaytutorials]

Sir, Parabola represents quadratic polynomial not a quadratic equation.

he sound like one of the characters in the 3 idiots lol

[christiancardenas]

Hay salamat i did understand the real life situation quadratic

[manivannans]

Please reply
Me ...sir it's very important to me...

bro fix my internet connection dont teach me math

Plz don't only watch the video like it too it will hardly take 1 millisecond of your like we should support Indian youtubers for every one like for India youtubers you are making our country atmanirbhar
