What are the roots of this function? f(x) = x2 – 8x + 12 a) {2, 6} b) {8, 12} c) {-3, -4} d) {-4, -4}

A

Step-by-step explanation:

We can find the roots of this function by factoring the trinomial and setting each factor equal to 0 to solve for x.

Trinomials are three term algebraic expressions typically featuring variables to exponent powers. To break these trinomials down we factor them using the diamond method or GCF. The diamond method states that for a trinomial multiply a*c then find two numbers which multiply to this number and add to b. When you find those numbers, write them as .

a=1, c=12

ac=12 and add to b=-8 which are -2 and -6

So (x-2)(x-6) are the factors. We set each equal to 0 and solve for x.

(x-2)=0

x=2

(x-6)=0

x=6

{2,6} are the roots of the function.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
