Question

Write x2 - 6x + 7 = 0 in the form (x - a)2 = b, where a and b are integers.

Answer 1

for \(x^2+bx+c=0\) we have \((x-\frac{-b}{2})=(\frac{b}{2})^2-c\)

Answer 2

?

Answer 3

do you see that if you know what b and c are you can use that form to get the answer?

Answer 4

oh. thx

Answer 5

so for you b = -6, and c = 7

Answer 6

sorry, i don't get how i solve with the x

Answer 7

hold on...

Answer 8

i got 21... i did it wrong

Answer 9

\((x-\frac{-(-6)}{2})^2=(\frac{6}{2})^2-7\)

Answer 10

\((x-3)^2=2\)

Answer 11

you are not trying to get a number....reread the question.

Answer 12

oh. no, u got it. thank you so much :)

Answer 13

i get it now. thx
