Question

Solve the equation for all real solutions. 9x^2+30x+25= 0

Answer 1

Answer:

x = - $\frac{5}{3}$

Step-by-step explanation:

Given

9x² + 30x + 25 = 0 ← left side is a perfect square

(3x + 5)² = 0, thus

3x + 5 = 0 ⇒ 3x = - 5 ⇒ x = - $\frac{5}{3}$

solution is x = - $\frac{5}{3}$ with multiplicity 2
