Answer:
<h2>2x^3+3x^2</h2>
Step-by-step explanation:
<h3>x^2(2x+3)</h3><h3 /><h3>=(x^2)(2x+3)</h3><h3 /><h3>=(x^2)(2x)+(x^2)(3)</h3><h3 /><h3>=2x^3+3x^2</h3>
We have
x² + 24x = 17 (1)
Note that
(x + 12)² = x² + 24x + 144
By adding 144 to the left side of equation (1), it becomes a perfect square.
Therefore
x² + 24x = (x+12)² - 144 (2)
Substitute (2) into (1).
(x + 12)² - 144 = 17
(x + 12)² = 17 +144
(x + 12)² = 161
Answer:
We added 144 to the left side of equation (1) in order to make it a perfect square.
I think the answer be C? Sorry if it's wrong
