Hello there!

(x - 3)(x + 9) = -27
x² + 6x - 27 = -27
x² + 6x = -27 + 27
x² + 6x = 0
Factorize
x(x + 6) = 0
Now all we have to do is set the factors equal to 0
x = 0 or x+6 = 0
x = 0 or x = -6
Answer : x = 0 or x = -6

I don't know what the options they give you. But if you see 0 or 6 choose it.

I hope this help!

Find the equivalent expression of the following: x3 (x2 + 5x + 7)
Kay [80]

The equivalent expression of x^3 (x^2 + 5x + 7) is x^5 + 4x^4 + x^4 + 8x^3 - x^3

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

x^3 (x^2 + 5x + 7)

Expand the expression

x^3 * x^2 + x^3 * 5x + x^3 * 7

Evaluate the product

x^5 + 5x^4 + 7x^3

Expand the expression

x^5 + 4x^4 + x^4 + 8x^3 - x^3

Hence, the equivalent expression of x^3 (x^2 + 5x + 7) is x^5 + 4x^4 + x^4 + 8x^3 - x^3
