Question

Square root x+10=x-2

Answer 1

square both sides of the equation and simplify to get a quadratic equation

Answer 2

square both sides then factor or use quadratic equation.

Answer 3

it depends whether the quadratic will factor or not

Answer 4

x+ 10 = (x-2)^2
x + 10 = x^2 - 4x + 4
x^2 - 5x -6 = 0
will this factor?

Answer 5

we need two numbers which when multiplied give -6 and when added give -5

Answer 6

Yes! It factors!! So the quadratic formula and factoring will work. That's so cool!

Answer 7

yeah!
