Question

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

Answer 1

Answer:

Correct answer: $t^{2} + 3t -10$

Step-by-step 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
