Answer:
Changes made to your input should not affect the solution:
(1): "x2" was replaced by "x^2".
Step by step solution :
STEP
1
:
Equation at the end of step 1
(11x2 - 33x) + 218 = 0
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 11x2-33x+218
The first term is, 11x2 its coefficient is 11 .
The middle term is, -33x its coefficient is -33 .
The last term, "the constant", is +218
Step-1 : Multiply the coefficient of the first term by the constant 11 • 218 = 2398
Step-2 : Find two factors of 2398 whose sum equals the coefficient of the middle term, which is -33 .
-2398 + -1 = -2399
-1199 + -2 = -1201
-218 + -11 = -229
-109 + -22 = -131
-22 + -109 = -131
-11 + -218 = -229
-2 + -1199 = -1201
-1 + -2398 = -2399
1 + 2398 = 2399
2 + 1199 = 1201
11 + 218 = 229
22 + 109 = 131
109 + 22 = 131
218 + 11 = 229
1199 + 2 = 1201
2398 + 1 = 2399
Observation : No two such factors can be found !!
