Solution Steps

Step 1: Remove the Parentheses

Start by removing the parentheses. Remember to distribute the negative sign to each term inside the second set of parentheses: (−3x2+2x−5)−(−7x2+1)=−3x2+2x−5+7x2−1 \left(-3x^{2} + 2x - 5\right) - \left(-7x^{2} + 1\right) = -3x^{2} + 2x - 5 + 7x^{2} - 1

Step 2: Combine Like Terms

Combine the terms that have the same variable and exponent: −3x2+7x2+2x−5−1 -3x^{2} + 7x^{2} + 2x - 5 - 1

Step 3: Simplify the Expression

Perform the arithmetic operations on the like terms: (−3x2+7x2)+2x+(−5−1)=4x2+2x−6 (-3x^{2} + 7x^{2}) + 2x + (-5 - 1) = 4x^{2} + 2x - 6

Final Answer

4x2+2x−6\boxed{4x^{2} + 2x - 6}
