Pulling out like terms

3.1 Pull out like factors :

5x2 + 70x + 245 = 5 • (x2 + 14x + 49)

Trying to factor by splitting the middle term

3.2 Factoring x2 + 14x + 49

The first term is, x2 its coefficient is 1 .

The middle term is, +14x its coefficient is 14 .

The last term, "the constant", is +49

Step-1 : Multiply the coefficient of the first term by the constant 1 • 49 = 49

Step-2 : Find two factors of 49 whose sum equals the coefficient of the middle term, which is 14 .

-49 + -1 = -50

-7 + -7 = -14

-1 + -49 = -50

1 + 49 = 50

7 + 7 = 14 That's it
