$= 8 x^{2} + 2 x - 15$ $=8x^2+2x-15$

Explanation:

$= (- 4 x \times - 2 x) + (- 4 x \times - 3) + (5 \times - 2 x) + (5 \times - 3)$ $=(-4x xx-2x)+(-4x xx-3)+(5xx-2x)+(5xx-3)$
$= 8 x^{2} + 12 x - 10 x - 15$ $=8x^2+12x-10x-15$
$= 8 x^{2} + 2 x - 15$ $=8x^2+2x-15$

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

FIRSTS:
$- 4 x \times - 2 x$ $-4x xx -2x$ $\to 8 x^{2}$ $rarr color(blue)(8x^2$

OUTERS:
$- 4 x \times - 3$ $-4x xx -3$ $\to 12 x$ $rarr color(purple)(12x$

INNERS:
$5 \times - 2 x$ $5 xx -2x$ $\to - 10 x$ $rarr color(brown)(-10x)$

LASTS:
$5 \times - 3$ $5 xx -3$ $\to - 15$ $rarr color(green)(-15$

Now put them all together and simplify:

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

$8 x^{2} + 2 x - 15$ $8x^2 + 2x - 15$
