Question

solve the quadratic equation using factorisation method :x²+7x-18=0

Answer 1

Hey mate !!

Here's your answer !!

Factorisation method:

Equation :- x² + 7x -18 = 0

= x² + 9x - 2x - 18 = 0

= x ( x + 9 ) - 2 ( x + 9 ) = 0

= ( x - 2 ) ( x + 9 ) = 0

=> x = 2, -9

Hope my answer helped !!

Cheers !!
