Answer:

x = -4

Step-by-step explanation:

2x² + 8x = x² - 16

x² + 8x + 16 = 0

x² + 4x + 4x + 16 = 0

x(x + 4) + 4(x + 4) = 0

(x + 4)² = 0

x = -4

(a+2b)² ?????????????????????<br>

lbvjy [14]

Answer:

a² + 4ab + 4b²

Step-by-step explanation:

Given

(a + 2b)²

= (a + 2b)(a + 2b)

Each term in the second factor is multiplied by each term in the first factor, that is

a(a + 2b) + 2b(a + 2b) ← distribute both parenthesis

= a² + 2ab + 2ab + 4b² ← collect like terms

= a² + 4ab + 4b²
