Question

Simplify using the horizontal method (t2-6t+3)(2t-5)

Answer 1

lll

Explanation:

Answer 2

1. First write the two polynominals in a row separated by using multiplication sign.

`(t^2-6t+3)\cdot(2t-5)`

2. Multiply each term of one binomial with each term of the other.

`=(t^2)(2t)+(t^2)(-5)+(-6t)(2t)+(-6t)(-5)+(3)(2t)+(3)(-5)\\\\=2t^3-5t^2-12t^2+30t+6t-15`

3. In the product obtained, combine the like terms and then add the like terms.

`=2t^3-5t^2-12t^2+30t+6t-15\\\\=(2t^3)+(-5t^2-12t^2)+(30t+6t)+(-15)\\\\=2t^3-17t^2+36t-15`
