Multiplying Polynomials......
Do you have a question? Use the general rule
(a + b)(c + d) = ac + ad + bc + bd
Form all possible products of terms in the two polynomials, and add them
Find the product
(2x)(10x)
The product of (2x)(10x) is:
(2x)(10x) = 20x^2
-3m(m + 8)
-3m(m + 8) can be simplified using the distributive property:
-3m(m + 8) = -3m * m - 3m * 8
= -3m^2 - 24m
So, the simplified form of -3m(m + 8) is -3m^2 - 24m.
4d(2d - 9)
To solve, use the distributive property:
4d(2d - 9) = (4d * 2d) - (4d * 9)
= 8d^2 - 36d
So, the simplified form of 4d(2d - 9) is 8d^2 - 36d.
(3x + 4)(x -2)
To solve, use the distributive property:
(3x + 4)(x - 2) = 3x * x - 3x * 2 + 4 * x - 4 * 2
= 3x^2 - 6x + 4x - 8
= 3x^2 - 2x - 8
So, the simplified form of (3x + 4)(x - 2) is 3x^2 - 2x - 8.
(2y - 1)(4y - 3)
To solve, use the distributive property:
(2y - 1)(4y - 3) = 2y * 4y - 2y * 3 - 1 * 4y + 1 * 3
= 8y^2 - 6y - 4y + 3
= 8y^2 - 10y + 3
So, the simplified form of (2y - 1)(4y - 3) is 8y^2 - 10y + 3.
