Question

Solve the equation x2 – 4x – 12 = 0 by graphing.

Answer 1

the answer is x = -6

to graph this, draw a point at (-6, 0) and (-8, 4)

Answer 2

Answer:

x = -2, x = 6

Step-by-step explanation:

x²-4x-12 = 0

Make a table with x, and y values.

Graph the parabola.

The solutions of equation are

the points where the graph intersects the x-axis.

x = -2, x = 6
