Answer:

Step-by-step explanation:

We want to find:

$(x^2+2x-3)(4x^2-5x+6)$

Distribute:

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

Distribute:

$=(4x^4+8x^3-12x^2)+(-5x^3-10x^2+15x)+(6x^2+12x-18)$

Rearrange:

$=(4x^4)+(8x^3-5x^3)+(-12x^2-10x^2+6x^2)+(15x+12x)+(-18)$

Combine like terms:

$=4x^4+3x^3-16x^2+27x-18$

The answer is D.
