Question

how do I extract the square roots in 2(x-5)^2 = 17

Answer 1

2(x^2+25-10x)=17

do it urself after it

Answer 2

isn't that just factoring?

Answer 3

yes

Answer 4

but that's not extracting the square :(

Answer 5

and it doesn't factor nicely.

Answer 6

2x^2-20x+8

Answer 7

+8? 25(2) = 50
-17
= 33

Answer 8

x^2-10x+4
you must rooting

Answer 9

oh no you do this in two steps only

Answer 10

\[2(x-5)^2=17\]
\[(x-5)^2=\frac{17}{2}\]
\[x-5=\pm\sqrt{\frac{17}{2}}\]
\[x=5\pm\sqrt{\frac{17}{2}}\]
