Answer & Step-by-step explanation:
<em>(x² - 5x)(2x² + x - 3)</em>
Multiply each term from the first expression into the second expression.
<em>2x⁴ + x³ - 3x² - 10x³ - 5x² + 15x</em>
Combine like terms.
<em>2x⁴ - 9x³ - 8x² + 15x</em>
So, after you multiply the expressions, your answer will be 2x⁴-9x³-8x²+15x.
1. Rename the mixed numbers with common denominators
2. Add the mixed numbers together to get 15 4/6
3. Subtract the sum from 26 to get 10 1/2
4. Since the only term left on the left is k so k=10 1/2
