x^2+13x-160 verify them and Factorize
Answers
Answer:
x =(13-√809)/2=-7.721
x =(13+√809)/2=20.721
Step-by-step explanation:
Trying to factor by splitting the middle term
1.1 Factoring x2-13x-160
The first term is, x2 its coefficient is 1 .
The middle term is, -13x its coefficient is -13 .
The last term, "the constant", is -160
Step-1 : Multiply the coefficient of the first term by the constant 1 • -160 = -160
Step-2 : Find two factors of -160 whose sum equals the coefficient of the middle term, which is -13 .
-160 + 1 = -159
-80 + 2 = -78
-40 + 4 = -36
-32 + 5 = -27
-20 + 8 = -12
-16 + 10 = -6
-10 + 16 = 6
-8 + 20 = 12
-5 + 32 = 27
-4 + 40 = 36
-2 + 80 = 78
-1 + 160 = 159
