Terri makes a quilt using three sizes of fabric squares the side lenght of each fabric square is the square root of the area

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
