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

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

their is no graph showing
