Solve using the quadratic formula with complex solutions

👉 Learn how to solve quadratic equations using the quadratic formula. A quadratic equation is an equation whose highest power on its variable(s) is 2. The quadratic formula is a formula which can be used to find the roots of (solve) a quadratic equation.

The quadratic formula is given by x = (-b +/- sqrt(b^2 - 4ac)) / 2a, where a is the coefficient of the quadratic term (x^2), b is the coefficient of the linear term (x) and c is the constant term. Thus, to solve a quadratic equation using the quadratic formula, first identify the 'a', 'b' and the 'c' of the quadratic equation and plug them into the quadratic formula and evaluate accordingly.

We can't put 'i' inside the square root.

[poojajuneja]

How many solutions are there to equation x= 1 ??

[movieentertainment]

If we subtract 2x square to -x square what is the answer please tell I am pretty confuse

[himanshucharkvorty]

If x^4=0 then X should have 4 roots but in the case X have only 1 root
Please answer why

[mandeepsandhu]

I think that it is 1+under root of 5/ 2

[jadeochoa]

the square root of -1 is 'i' meaning it is no longer under the radical sign the 'i' should be in front of the square root of 3

Hey 👋 2x^– 5x– 7 =0 I really need to get the answer for this

[neowise]

So the roots are alpha = 1+i√3/2
And beta = 1-i√3/2

[shikhaagrawal]

this is wrong
roots will not have root3 i, it ll just be 3 i

[moisesjimenez]

le falto el simbolo negativo en la formula cuadratica en el -1 por lo tanto el resultado es erroneo y esta malo
