The answer that I got was t(3t^2 + 2) / 2 but the answer stated was t((3/2)t^2 + 1).

lim x→3 (x3 − 13x2 + 51x − 63) / (x3 − 4x2 − 3x + 18) = a / 5 Find the value of a. (It is supposue to be -4. Why?)

Factor the polynomial / trinomial x^2+5x+6 show work

I need to completely factor the polynomial. If it can't, I need to know if it is prime.

How to factor

The long side of a rectangle is 3x+21 units, and it's area is 3x^2+33x+84. Find the width

I know how to do factoring with an exponent of 2 after the coefficent but i'm confused at how to do ones squared such as: 27x^3+125 Thank you
