Answers
Answer:
X+1=180*3x
X+1=540x
1=540x-x.
1=539x
X=539/1
X=539

Step-by-step explanation:
Factoring x2+3x-1 180
The first term is, x2 its coefficient is 1.
The middle term is, + 3 * x its coefficient is 3.
The last term, "the constant", is -180
Step-1: Multiply the coefficients of the first term by the constant 1 * - 180 = -180
Step-2 : Find two factors of -180 whose sum equals the coefficient of the middle term, which is 3.
-180 + 1 = -179
-90 + 2 = -88
-60 + 3 = -57
-45 + 4 = -41
-36 + 5 = -31
-30 + 6 = -24
-20 + 9 = -11
-18 + 10 = -8
-15 + 12 = -3
-12 + 15 = 3
That's it
Step-3: Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -12 and 15 x2-12x+15x-180
Step-4 : Add up the first 2 terms, pulling out like factors:
x*(x-1 12)
Add up the last 2 terms, pulling out common factors:
15(x - 12)
Step-5: Add up the four terms of
step 4: (x + 15)(x - 12) Which is the desired factorization
