Question

find the product (x-8)(5+2x)​

Answer 1

$\huge\huge\frak{\color{red}{Answer:-}}$

${2x}^{2} - 11x - 40$

$\large\bold\color{tan}{\underbrace{Explanation}:-}$

$\color{aqua}{(x - 8)(5 + 2x)}$

$= > x(5 + 2x) - 8(5 + 2x)$

$= > 5x + 2 {x}^{2} - 40 - 16x$

$= > {2x}^{2} + 5x - 16x - 40$

$= >{2x}^{2} - 11x - 40$

Answer 2

Answer :-

= 3x (5 – 2x) + 8(5 – 2x)

= 3x × 5 – 3x × 2x + 8 × 5 – 8 × 2x

= 15x – 6x2 + 40 – 16x

= – 6x2 + 15x – 16x + 40

= – 6x2 – x + 40
