Whit all of them i can’t fail math it’s the only subject i’m failing in my mama would whoop me

Find the zeros of the function. write the smaller solution first, and the larger solution second f(x)= (x+6)^2-49

How to do this , and can some one explain

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
