Question

Multiply the binomials:
(2x+5)*(4x-3)

Answer 1

$2x \: (4x - 3) \: + 5 \: (4x \: - 3) \\ 8x {}^{2} - 6x + 20x - 15 \\ 8x {}^{2} + 14x - 15$

Answer 2

(2x+5)(4x-3) = $8x^2+14x-15$

Step-by-step explanation:

Given:

We have,

(2x+5)(4x-3)

= 2x (4x-3) + 5 (4x-3)

= $(2x\times 4x)-(2x\times 3)+(5\times 4x)-(5\times3)$

= $8x^2-6x+20x-15$

= $8x^2+14x-15$
