Question

Expand and simplify 2(5x+3)−2(x 2 −3) ​ =10x+6−(2(x 2 −3))= =10x+6−(2x 2 −6)= =10x+6−2x 2 +6= =−2x 2 +10x+12 ​

Answer 1

-2x² + 10x - 12

Explanation:

Given the expression 2(5x+3)−2(x^2 −3) ​

Expand

2(5x+3)−2(x^2 −3) ​

= 2(5x)+2(3) -2(x²)-2(-3)

= 10x + 6 - 2x²+6

= 10x -2x²+12

Express in standard form

= -2x² + 10x - 12
