17:30 min the sir starts to solve word problems so if u know u are good in factorisation then u can directly go on word problems....bless me for helping u
Wishing all my friends who are 10 grade 20-2023 batch should get above 90+💖

53:53 answer of homeworks question - length -7m and breadth -4m

Let's solve it by linear equations
Breadth = B
Length = L
B = L-3 ( Given)

Let's find area 1/2 × (L-3)×12 = (6L-18)

Let's add 4 more (6L-18) +4 = (6L-14)

Area of Rectangle :-
L(L-3) = 6L-14
L²-9L+14
By Quadratic formula
We will get 2 solutions 2 and 7
2 isn't practically possible hence we will consider 7

Length = 7
Breadth = 7-3 = 4

Thanks

A nightmare question for me at 10:00 🙂❤️
Khatarnak sir. Neend nhi aa rhi thi Bina solve kiye toh maine haar man kar factorisation wala method dekh hi liya ...
Quadratic formula se toh maine 3 step me hi khatam kar diya tha...
☺️👍☺️👍☺️👍☺️👍☺️👍
Happy New year sir 2022.❤️

Homework question answer length of rectangular park is 7m
And breadth of a rectangular✈️✈️✈️ park is 4m. Very easy

54:30 Solution of the Homework Problem:
let length be x & breadth be (x-3)
So, the equation so formed is: x^2-3x=6x-14
X^2-9x+14=0 Therefore, (x-7)(x-2) are the solutions
So, we can say that x=7 is the length because the value of x can never be less than 3 i, e. breadth=x-3
Hence, length=7m & breadth=7-3=4m

breadth=x-3
length=x
area of the rectangle =4+(area of the triangle)
area of the triangle =1/2(b x h)= 1/2(x-3)(12)=(x-3)(6)=6x-18
area of the rectangle=4=6x-18=6x-14
area of rectangle formula =l x b
so, 6x-14=(x-3)(x)
6x-14=x^2-3x
AFTER SIMPLIFICATION,
x^2-9x+14=0
AFTER SOLVING,
(X-7)=0 & (X-2)=0
X=7 &X=2
IF WE CHECK WITH THE BREADTH,
breadth=x-3
if x=7,
7-3=4

ifx=2,
2-3=-1
because the measurement cannot be in the negative we take the x value as
length=7
breadth=4

The answer of homework questions is x=7 means length is 7 and breadth (x-3) that is 7-3=4
