Using the quadratic equation formula: x = 8.42 or x = -1.42
No, it is not.No, it is not.
{-1,7}
The solutions to the quadratic equation are: x = -1 and x = 6
If you are solving for y, it is fine. If you are solving for x, divide both sides by x and the equation should be x = y/x

k = sqrt(160) = 12.6
6.50 to the nearest hundredth (4.685 & 1.815)

This simplifies to x2 + 10x + 17 = 0 which has no solution in integers. Quadratic formula gives roots as -2.17 and -7.83 to the nearest hundredth. If the original equation had been "equals 0" rather than "equals 8", there would have been only one root: x = -5
No, It's a a quadratic equation because you have X squared.
It is a quadratic equation in X.
no, because xx=x squared, and x squared is not linear
