Question

Would these simplified expressions by equivalent to these expressions: i)f(x)=-3(x+2)^2
ii)f(x)=x^2-x-2 / 3x^2+4x+1

Simplified expressions:
i)-3x^2-13x-13
ii)(x-2)(3x+1)

Please help me!

Answer 1

(x+2)^2 = x^2+4x+4
So, the first is clearly not the same

(x-2)(x+1) / (3x+1)/(x+1)
= (x-2)/(3x+1)
So, except for the missing division symbol, the 2nd is ok.
