Write two like terms using whatever variable(s) you'd like. Be sure to include exponents. And please explain why these are like terms. Thank you! :)

Like terms are terms whose variables are the same.

So, if my variable for the first term is x² then the the variable for the second term should also be x², similarly, if the variable for the first term is u⁷ then the the variable for the second term should also be u⁷. Only then, the terms will be considered like terms.

Eg: 56t⁴, 6t⁴

-g², -109g²

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
