Question

a, 2x( 2x-1) -(2x-1)

b, 2x( 4x + 2x + 1) - ( 4x + 2x +1)

Answer 1

a)2x( 2x-1) -(2x-1)

=(2x-1)(2x-1)

=(2x-1)²

b)2x( 4x + 2x + 1) - ( 4x + 2x +1)

=(2x-1)(4x+2x+1)

=(2x-1)(6x+1)

Answer 2

a) \(2x\left(2x-1\right)-\left(2x-1\right)=\left(2x-1\right)\left(2x-1\right)\)

b) \(2x\left(4x+2x+4\right)-\left(4x+2x+4\right)=\left(2x-1\right)\left(4x+2x+4\right)\)
