:

Trying to factor by splitting the middle term

1.1 Factoring x2-100x+1600

The first term is, x2 its coefficient is 1 .

The middle term is, -100x its coefficient is -100 .

The last term, "the constant", is +1600

Step-1 : Multiply the coefficient of the first term by the constant 1 • 1600 = 1600

Step-2 : Find two factors of 1600 whose sum equals the coefficient of the middle term, which is -100 .

-1600 + -1 = -1601

-800 + -2 = -802

-400 + -4 = -404

-320 + -5 = -325

-200 + -8 = -208

-160 + -10 = -170

-100 + -16 = -116

-80 + -20 = -100 That's it
