Complete the steps in solving the quadratic function 7x-9=7x^2-49x by completing the square

7x-9=7x^2-49x

-7x              -7x

-9=7x^2-56x

-9=7(x^2-8x+c)-7(c)

c=(-8/2)^2=(-4)^2=16

-9=7(x^2-8x+16)-7(16)

+112                    +112

103=7(x-4)^2

/7     /7

103/7=(x-4)^2

sqrt      sqrt

+/-=x-4

+4              +4

x=+4=3.836+4=7.836

x=4-=4-3.836=0.164

x=7.836, x=0.164

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
