Question

how to factor t^2 +3t-40?

Answer 1

Find two numbers which when:
Multiplied together give -40.
Added together give 3.

The easiest way to start would be to write down the factors of -40. Can you proceed from here?

Answer 2

Once you have found them (call the two numbers a and b) you can factor it in the form (x+a)(x+b)

Answer 3

so the answer would be (t-5)(t+8) right?
