Answer:
You make a factor tree for (-)40 where the factors of -40 are -8 and +5. This becomes (x+5)(x-8) which can be multiplied to get back to the starting point.
Answer:
Write the factors and add them up.
Step-by-step explanation:
To factorize the given trinomial [tex]x^2-3x-40[/tex], you first need to find the factors of -40 such that when multiplied they give -40 and when added they give a result of -3.
The second step in the process of factoring is to write the add the factors up in place of '-3x' to get:
[tex] x^{2} - 8x + 5x - 40 [/tex]
