Question

1. Factorise 3x2 + 4x – 4

Answer 1

Step-by-step explanation:

3x

3x 2

3x 2 −4x−4

3x 2 −4x−4=3x

3x 2 −4x−4=3x 2

3x 2 −4x−4=3x 2 −6x+2x−4 (Rewrite −4x as −6x+2x to make grouping and factoring easier.)

3x 2 −4x−4=3x 2 −6x+2x−4 (Rewrite −4x as −6x+2x to make grouping and factoring easier.)=3x(x−2)+2(x−2)

3x 2 −4x−4=3x 2 −6x+2x−4 (Rewrite −4x as −6x+2x to make grouping and factoring easier.)=3x(x−2)+2(x−2)=(3x+2)(x−2)

3x 2 −4x−4=3x 2 −6x+2x−4 (Rewrite −4x as −6x+2x to make grouping and factoring easier.)=3x(x−2)+2(x−2)=(3x+2)(x−2)Therefore 3x

3x 2 −4x−4=3x 2 −6x+2x−4 (Rewrite −4x as −6x+2x to make grouping and factoring easier.)=3x(x−2)+2(x−2)=(3x+2)(x−2)Therefore 3x 2

3x 2 −4x−4=3x 2 −6x+2x−4 (Rewrite −4x as −6x+2x to make grouping and factoring easier.)=3x(x−2)+2(x−2)=(3x+2)(x−2)Therefore 3x 2 −4x−4=(3x+2)(x−2)
