X² <span>− 3x − 70=0
</span>x² + 7x - 10x − 70=0
x(x+7) - 10(x+7) = 0
(x+7)(x-10) = 0
x + 7 = 0 or x - 10 = 0
x = -7 x = 10
Answer: x=-7, x=10
Given :
- The length of a rectangle is 4m more than the width.
- The area of the rectangle is 45m²
⠀
To Find :
- The length and width of the rectangle.
⠀
Solution :
We know that,

So,
Let's assume the length of the rectangle as x and the width will be (x – 4).
⠀
Now, Substituting the given values in the formula :







⠀
Since, The length can't be negative, so the length will be 9 which is positive.
⠀
