So 64/100 /2=32/50 then 32/50 /2=16/25 so 1 16/25
Like terms are terms that are the exact same excluding the coefficient.
The answer here would be 7y^3+8y^2-11y
The only like terms here are y. y^3 and y^2 aren't the same because they have different exponents
I hope this helps you
(f+g)(x)=2x+1+x^2-7
(f+g)(z)=x^2+2x-6
