can some one help with this polynomial.
(C -5)-^2
It would help if you proofread your questions before you post them. What is the base of the exponent 2?
What help do you want?
what would be the answer
Of course, I can help you with that! The expression you provided is (C - 5)^2. To simplify this polynomial, we need to apply the concept of expanding a binomial squared.
To expand a binomial squared, we use the formula (a - b)^2 = a^2 - 2ab + b^2. In this case, our binomial is (C - 5), so we substitute "a" with C and "b" with 5.
Now, let's substitute the values into the formula:
(C - 5)^2 = C^2 - 2(C)(5) + 5^2
Simplifying further:
(C - 5)^2 = C^2 - 10C + 25
Therefore, the simplified form of the polynomial (C - 5)^2 is C^2 - 10C + 25.
