Answer:
2x^4 - x^2 + 26x - 15
Step-by-step explanation:
To multiply the polynomials, use the distributive property to multiply each term. As you do so, be sure to change exponents accordingly by adding them as you multiply each term.
(2x2 + 4x - 3)(x2 - 2x + 5)
2x^4 + 4x^3 -3x^2 - 4x^3 - 8x^2 + 6x +10x^2 + 20x - 15
2x^4 + 4x^3 - 4x^3 - 3x^2 - 8x^2 +10x^2 + 20x + 6x - 15
2x^4 - x^2 + 26x - 15
