Write an equation in which the quadratic expression 2x^2-2x-13 equals 0 show the expression in factored form and explain what your solutions mean for the equation. show ur work

x = 3 and -2 are the two solutions.

Step-by-step explanation:

2x^2 -2x -12 = 0

First factor out a 2

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

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

2 = 0 x - 3 = 0 x + 2 = 0

2 does not equal zero so this is an extraneous solution

x - 3 = 0 so x = 3

x + 2 = 0 so x = -2

3 blue cups and 9 red cups

Step-by-step explanation:

it needs to be in a ratio of 1:3 so for every 1 cup of blue there is 3 cups of red.

its the same ratio as the other two
