Question

Solve for x: (x – 4)2 = 2

Answer 1

r u squaring that or multiplying?

Answer 2

\[(x-4)^2 =2\]
is this your question?

Answer 3

(x-4)2=2
2x-8=2
2x=8+2
2x=10
\[2x \div2=10\div2\]
x=5

Answer 4

dat is if your question is multiplying 2

Answer 5

it is ^2

Answer 6

then its:
(x-4)(x+4)=2
x(x+4)-4(x+4)=2
\[x ^{2}+4x-4x-16=2\]
\[x ^{2}-16=2\]
\[x ^{2}=16+2\]
\[x ^{2}=18\]
now you square both sides and the square root will cancel the ^2 on x
\[x=\sqrt{18}\]
x=4.24

Answer 7

or \[3\sqrt{2}\] its the same but the other answer was in decimals

Answer 8

If that's an exponent, \((x-4)^2=2\), then \(x-4=\pm\sqrt{2}\), so \(x=4\pm\sqrt{2}\).

Answer 9

no you solve the set that is (x-4)^2 as different of 2 squares,then you equate it to 2
