Question

I don’t really understand what is wrong with this problem or what to do?

Answer 1

Correct answer:
`t^(2) + 3t -10`

Explanation:

(t - 2)(t + 5)

First you have to distribute the numbers in the bracket

• The first number of the first bracket multiplied by the first number in the second bracket
• the first number of the first bracket multiplied by the second number of the second bracket
• the second number of the first bracket multiplied by the first number of the second bracket
• the second number of the first bracket multiplied by the second number of the second bracket

(t x t)(t x 5)(-2 x t)(-2 x 5) =

`t^(2) + 5t - 2t -10` = (subtract the like terms)

`t^(2) (+5t - 2t) -10` =

`t^(2) + 3t - 10`

I hope this helped
