Question

find x if
$0 = {x}^{2} + ( - 2x) - 35$
Give answer if u know......​

Answer 1

Answer:

X²-2x-35=0

if you factorize you get

(x-7)(x+5) =0

therefore

X= 7 or -5

Answer 2

SOLUTION :

x² + ( - 2x ) - 35 [GIVEN]

= x² - 2x - 35 = 0

= x² - 7 x + 5 x - 35 = 0

= x ( x -7 ) + 5 ( x - 7 ) = 0

= ( x - 7 ) ( x + 5 ) = 0

( x- 7 ) = 0 , ( x + 5 ) = 0

x = 7. , x = -5
