Poly x Mono
To multiply a polynomial by a monomial, you use the distributive property together with the laws of exponents for multiplication.Examples: Simplify.
2x(5x2 6x + 8)
2x(5x2 + 6x + 8)
(2x)(5x2) + (2x)(6x) + (2x)(8)
10x3 + 12x2 + 16x
10x3 + 12x2 16x

Poly x Mono
To multiply a polynomial by a monomial, you use the distributive property together with the laws of exponents for multiplication.Examples: Simplify.
3x2(2x2 + 3x 12)
3x2(2x2 + 3x + 12)
(3x2)(2x2) + (3x2)(3x) + (3x2)(12)
6x4 + 9x3 + 36x2
6x4 9x3 + 36x2
