Trying to factor by splitting the middle term
2.1 Factoring 3x2-2x-5
The first term is, 3x2 its coefficient is 3 .
The middle term is, -2x its coefficient is -2 .
The last term, "the constant", is -5
Step-1 : Multiply the coefficient of the first term by the constant 3 • -5 = -15
Step-2 : Find two factors of -15 whose sum equals the coefficient of the middle term, which is -2 .
-15 + 1 = -14
-5 + 3 = -2 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and 3
3x2 - 5x + 3x - 5
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (3x-5)
Add up the last 2 terms, pulling out common factors :
1 • (3x-5)
Step-5 : Add up the four terms of step 4 :
(x+1) • (3x-5)
Which is the desired factorization
Equation at the end of step
2
:
(3x - 5) • (x + 1) = 0

Theory - Roots of a product
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
