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

Mathematics
1 answer:
UkoKoshka [18]4 years ago
7 0

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
