Suppose f(x) = x square -8x +20 find x such that f(x) =24
a.) x={3+- 3 square root of 2}
b.) x= {-4 +- 2 square root of 5}
c.) x= {-3+- 3 square root of 2}
d.) x={ 4+- 2 square root of 5}

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
