Step-by-step explanation:
4x² + 8x − 7 = 0
4x² + 8x = 7
x² + 2x = 7/4
x² + 2x + 1 = 11/4
(x + 1)² = 11/4
x + 1 = ±√(11/4)
x = -1 ± √(11/4)
Y has already been solved for.
This equation is written in slope-intercept form. (y = mx + b)
In this case m = 2 and b = -3
Slope = 2
Y-intercept = -3
Hope This Helped! Good Luck!
