Question

20 points ! !!! 3. Write an equation in which the quadratic expression 2x^ -2x -12 equals 0. Show the expression in factored form and explain what your solutions mean for the equation. Show your work.

Answer 1

Answer:

see below

Step-by-step explanation:

2x^2 -2x-12 = 0

Factor out 2

2(x^2 - x -6) = 0

Factor inside the parentheses

2( x-3)(x-2)=0

Using the zero product property

x-3 =0   x-2=0

x=3   x=2

The graph crosses the x axis when x=3 and x=2
