Answer:
x(x+y+3)(x+y-3)
Step-by-step explanation:
x³+2x²y+xy²-9x
= x((x²+2xy+y²)-3²)
= x((x+y)² - 3²)
= x(x+y+3)(x+y-3)

Answer:
The expression equivalent to 8 - (6r + 2) is -6r + 6 ⇒ A
Step-by-step explanation:
Let us solve the question
∵ The expression is 8 - (6r + 2)
→ Multiply the bracket by (-)
∵ (-) × (+) = (-)
∴ 8 - (6r + 2) = 8 - 6r - 2
→ Add the like terms
∵ 8 - (6r + 2) = (8 - 2) - 6r
∴ 8 - (6r + 2) = 6 - 6r
→ Switch the terms
∴ 8 - (6r + 2) = -6r + 6
∴ The expression equivalent to 8 - (6r + 2) is -6r + 6
