Answer:

2x(5x + 14) + 15

Step-by-step explanation:

Given: (2 $x^{2}$ + 3)(4x + 5) - 8x( $x^{2}$ - 2)

(2 $x^{2}$ + 3)(4x + 5) - 8x( $x^{2}$ - 2) = 2 $x^{2}$ (4x + 5) + 3(4x + 5) - 8x( $x^{2}$ - 2)

= (8 $x^{3}$ + 10 $x^{2}$ + 12x + 15) - 8 $x^{3}$ + 16x

= 8 $x^{3}$ + 10 $x^{2}$ + 12x + 15 - 8 $x^{3}$ + 16x

collecting like terms to have,

8 $x^{3}$ - 8 $x^{3}$ + 10 $x^{2}$ + 12x + 16x + 15

10 $x^{2}$ + 28x + 15

Thus,

(2 $x^{2}$ + 3)(4x + 5) - 8x( $x^{2}$ - 2) = 10 $x^{2}$ + 28x + 15

= 2x(5x + 14) + 15
