-
(5x + 1)(3x + 5) = 15x^2 + 28x + 5
The square root of anything to the second power is just that anything, so the second equation becomes 2x - 5 = 13
2x = 13 + 5
2x = 18
x = 9
x^2 + 5x - 14 = 0
(x - 2)(x + 7) = 0
The graph crosses the x - axis (the y-value is zero) at x = 2 and x = -7
x^2 + 4x - 21 = 0
(x + 7)(x - 3)
The roots are x = -7 and x = 3
