Equation at the end of step 1
((5•7x2) - 24x) - 4
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 35x2-24x-4
The first term is, 35x2 its coefficient is 35 .
The middle term is, -24x its coefficient is -24 .
The last term, "the constant", is -4
Step-1 : Multiply the coefficient of the first term by the constant 35 • -4 = -140
Step-2 : Find two factors of -140 whose sum equals the coefficient of the middle term, which is -24 .
-140 + 1 = -139
-70 + 2 = -68
-35 + 4 = -31
-28 + 5 = -23
-20 + 7 = -13
-14 + 10 = -4
-10 + 14 = 4
-7 + 20 = 13
-5 + 28 = 23
-4 + 35 = 31
-2 + 70 = 68
-1 + 140 = 139
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
35x2 - 24x - 4
