if you meant "x²+7x-80=0"
solution1 x≈6
solution2 x≈-13
if you meant "x²*7x-80=0"
x≈2
if you meant "x*2*7*x-80=0"
solution1 x≈2
solution2 x≈-2
if you meant "x²+7x-80"
unable to find x or simplify
if you meant exactly like you wrote "x*2*7*x-80"
then it could be simplified to 14x²-80 but I don't see how to solve this by graphing.

How do you solve x squared minus x minus 12?
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.

Find the sulotion set of 4a2-16a equals 0?
There are two answers in the solution set. To solve this we factor the left side to become 4a(a-4). This lets us get the 4. The other answers is 0. Set 4a=0 and solve for "a" and then a-4=0 and solve for "a."
