Write an equation in which the quadratic expression 2x^2 – 2x –12 equals 0. show the expression in factored form and explain what your solutions mean for the equation. show your work.

ANSWER

The x-intercepts are (-2,0) and (3,0)

EXPLANATION

The given quadratic expression is

We equate this to zero to get:

Divide through by 2 to get,

This implies that,

This means that the graph of

meets the x-axis at x=3 or x=-2

Step-by-step explanation:

2x^2 - 2x - 12 = 0

by using the factoring method (or any other method of your choice for quadratic equations), you can express the above as:

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

This means that either,

(2x-6) = 0  or (x+2) = 0

Working out the above 2 linear equations gives the possible solutions for x as x = -2 or x = 3

step-by-step explanation:

you have to multiply 1.53 by 12 so the equation is 12x1.53 and then that is your answer.

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
