Question

Solve by factoring
X^2+x=63

Answer 1

x = 3
`√(7- x)`

Explanation:

so what you do here is move the x to the other side.

X^2 = 63 - x

then you square root both sides

so
`\sqrt{x^(2) }` and
`√(63 - x)`

so you end up with

x =
`√(63 - x)`

so now we ask what can we take out? 9 times 7 is 63 and 9 is a perfect square so when we take the square root of that, we end up with

x = 3
`√(7- x)`

have a good day :)
