If the one root of the quadratic equation

is 2 then the other root is

½

Step-by-step explanation:

If 2 is a root:

a(2)² - 5(2) + 2 = 0

4a - 10 + 2 = 0

4a = 8

a = 2

2x² - 5x + 2 = 0

2x² - 4x - x + 2 = 0

2x(x - 2) - 1(x - 2) = 0

(x - 2)(2x - 1) = 0

x = 2, ½

do you have a picture of the table

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
