Answer:
4x^2 + 12x + 9.
Step-by-step explanation:
(2x+3)^2
= (2x+3)(2x+3)
= 2x(2x+3)+3(2x+3)
= 4x^2 + 6x + 6x + 9
= 4x^2 + 12x + 9.
Answer:
-2x² + 10x - 12
Step-by-step 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
