Question

(x-5) (2x+3) (2x-1)​

Answer 1

(x-5) (2x+3) (2x-1)

x(2x+3) -5(2x+3) (2x-1)

2x²+3x-10x-15(2x-1)

2x²-7x-15(2x-1)

2x(2x²-7x-15) -1(2x²-7x-15)

4x³-14x²-30x-2x²+7x+15

4x³-16x²-29x+15

x(4x²-16x-29+15)

x(4x²-16x-14)

Answer 2

Answer:

here its simple

Step-by-step explanation:

see

we multiply parentheses

we get (2x^2 + 3X - 10x- 15) * (2x-1)

we collect like terms

(2x^2 - 7x- 15)* (2x - 1)

we again multiply parentheses

we get

4x^3 - 2x^2 - 14x^2 + 7x - 30x + 15

collect like terms we get

4x^3 - 16x^2 - 23x+ 15
