There are several ways to solve x2-x-12. The easiest way, if you have a graphing calculator, is to put y = x2-x-12 and y = 0 into the graph and then solve for the intercepts. A way to do it without a graphing calculator is by factoring. x2-x-12 factors into (x-4) and (x+3). Then set (x-4) and (x+3) each equal to zero and solve. (x-4)=0 becomes x=4. (x+3)=0 becomes -3. Therefore, the answers are -3 and 4.

How do you solve 0 equals x squared minus ten x plus 16?
x^(2) - 10x + 16 = 0 Factors of '16', which are, 1,2,4,8,16. Select two numbers from this list that add/subtract to '10' . They are '2' and '8'. Setting up brackets ( x 2)(x 8) Since '16' is positive(+), then both signs must be the same. Since '10x' is negative (-) , then both signs are negative. Hence (x - 2)(x - 8 ) = 0 When x - 2 = 0 x = 2 & when x - 8 = 0 x = 8 So the two answers are ,2, & ,8, .
