To divide \(10x^2 + 35x + 25\) by \(2x + 5\), we can use polynomial long division. 1. Divide the leading term: \(10x^2\) by \(2x\) gives \(5x\). 2. Multiply \(5x\) by \(2x + 5\) to get \(10x^2 + 25x\). 3. Subtract \(10x^2 + 25x\) from \(10x^2 + 35x + 25\) which leaves us with: \[ (10x^2 + 35x + 25) - (10x^2 + 25x) = 10x + 25 \] 4. Now divide \(10x\) by \(2x\) which gives \(5\). 5. Multiply \(5\) by \(2x + 5\) to get \(10x + 25\). 6. Subtract \(10x + 25\) from \(10x + 25\) to find: \[ (10x + 25) - (10x + 25) = 0 \] So, the quotient is \(5x + 5\) and the remainder is \(0\). Quotient: \(5x + 5\) Remainder: \(0\)
