Question

Solve 96 = x2 +4x by factorisation method​

Answer 1

Answer:

96 = x^2 + 4x

x^2 + 4x - 96 = 0

x^2 + 12x - 8x - 96 = 0

(x^2 + 12x) - (8x + 96) = 0

x(x + 12) - 8(x + 12) = 0

(x - 8) (x + 12) = 0

x = 8     OR     x = -12

Step-by-step explanation:

Answer 2

Answer:

x2+4x-96

(x-8)(x+12)

x-8=0

x+12=0

x=8

x=-12

Step-by-step explanation:

Identify a, b and c in your equation and then find two numbers that when multiplied together equal c, and when added together equal b

x2+4x-96

Write your equation in factored form

(x-8)(x+12)

Set each factor equal to zero

x-8=0

x+12=0

x=8

x=-12
