Simplify (3x-5)^2

Problem

(3*x−5)2

Solution

1. Identify the expression as a square of a binomial in the form (a−b)2

2. Apply the formula for the square of a binomial, which is (a−b)2=a2−2*a*b+b2

3. Substitute a=3*x and b=5 into the formula.

4. Expand the terms by calculating (3*x)2 2*(3*x)*(5) and 5

5. Simplify the resulting terms to arrive at the final polynomial.

Final Answer

(3*x−5)2=9*x2−30*x+25
