Question

Multiply out and simplify:
(3x + 4) (2x - 1)

Answer 1

`6x^(2)+5x-4`

Explanation:

Apply the distributive property

`(a+b)(c+d)=ac+ad+bc+bd`

Therefore,

`(3x+4)(2x-1)=3x*2x+3x(-1)+4*2x+4(-1)`

`(3x+4)(2x-1)=6x^(2) +5x-4`

Answer 2

6x²+5x-4

Explanation:

`(3x+4)(2x-1)\\=6x^2-3x+8x-4\\=6x^2+5x-4`
