Write the expression 5x²-4-3x²+6x+8+5x- 13 in its simplifild form . find its value when x= -2 ​

Answer 1

$\red{\boxed{\boxed{ -23 }}}$

Step-by-step explanation:

Write the expression 5x²-4-3x²+6x+8+5x- 13 in its simplifild form . find its value when x= -2

= 5x² - 4 - 3x² + 6x + 8 + 5x - 13

= 5(-2)² - 4 - 3(-2)² + 6(-2) + 8 + 5(-2) - 13

= 5(4) - 4 - 3(4) - 12 + 8 - 10 - 13

= 20 - 4 - 12 - 12 + 8 - 10 - 13

= -8 + 8 - 10 - 13

= -23
