Question

x²+8x-9=0

Explain the first step you used to solve the given equation

Answer 1

YOUR QUESTION IS X²+8X-9=0.

NOW YOU CAN SEE -9 IN EQ.SO YOU HAVE TO MAKE THE FACTOR SO THAT BY MULTIPLYING YOU GET X COEFFICIENT AND BY SUBTRACTING YOU GET CONSTANT THAT IS -9.

X² -9X +X -9=0

X(X-9)+1(X-9)=0

(X+1)(X-9)=0

Answer 2

x² + 8x - 9 = 0

(x + 9)(x - 1) = 0

x + 9 = 0 or x - 1 = 0

x = 1 or -9
