Step-by-step explanation:
3 + 6b + 3b² = 3 (b² + 2b + 1) = 3 (b + 1)²
root: -1 if 3 + 6b + 3b² = 0 b = -1
Answer:
x = -3 +
, -3 - 
Step-by-step explanation:
Step 1: Isolate <em>x</em>'s
2x² + 12x = 7
Step 2: Factor
2(x² + 6x) = 7
x² + 6x = 7/2
Step 3: Complete the Square
x² + 6x + 9 = 7/2 + 9
(x + 3)² = 25/2
Step 4: Solve for <em>x</em>
√(x + 3)² = √25/2
x + 3 = 5√2/2
x = -3 ± 5√2/2
