Question

Solve by factorisation method: x2 + 2x - 35 = 0.​

Answer 1

Answer:

x2+7x-5x-35=0

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

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

x=5or-7

Answer 2

Answer:

x= -7 , 5

Step-by-step explanation:

x² + 2x -35=0

=> x² +(7-5)x - 35=0

=> x² + 7x - 5x - 35=0

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

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

therefore,

either, x+7 = 0. or, x-5 = 0

x = -7. x = 5

I hope it's understandable.
