There are several ways to find the zeros of a quadratic function. One of my favorite is to use a graphing calculator to graph it. The zeros can be read directly from the graph.
The zeros are -5 and 6.
(2, -6)
Step-by-step explanation:
y = -2 - 2x
5x + 3 (-2-2x) = - 8
5x - 6 - 6x = - 8
-x - 6 = 8
- 6 + 8 = x
2 = x
x = 2
y = -2 -2x
y = -2 -2(2)
y = -2 -4
y = -6
(x, y) = (2, -6)
