Answer:
D
Step-by-step explanation:
Given
2x² + 3x - 7 = x² + 5x + 39
Subtract x² + 5x + 39 from both sides
x² - 2x - 46 = 0 ← in standard form
with a = 1, b = - 2, c = - 46
Solve for x using the quadratic formula
x = (- (- 2) ±
) / 2
= ( 2 ± 
) / 2
= ( 2 ± 
) / 2
= ( 2 ± 2
) / 2
= 1 ±
The answer is D
