Question

Find the solution sets x^2+(x+1)^2=25 ?

Answer 1

move 25 to the left hand side and expand the (x+1)^2
so you get x^2+x^2+2x+1-25=0
simplify it to get
2x^2+2x-24=0
take the 2 out to get
2(x^2+x-12)=0
factorise to get 2(x+4)(x-3)=0
so the solution are x=-4 and 3

factorise to get 2(x

Answer 2

whoops sry, the last line was not intended haha.
