Question

Solving Quadratics by Factoring

Solve x^2 = 14x – 49 (Show work for medal)

Answer 1

rewrite it

x^2 - 14x + 49 = 0

its a perfect square so it should be easy to factorise... 2 factors of 49 that that are both negative and add to -14

Answer 2

@campbell_st
x2 = 14x – 49
= x2 - 14x + 49 =0
= (x-7)^2=0
= x=7?

Answer 3

yep... its that simple...

Answer 4

I thought it'd be harder....Ha
