5 - (3x^2 - 2x) (6 - 3x^2 + 2x)
Answers
Step-by-step explanation:
5-(3x2-2x)(6-3x2+2x)
Final result :
(3x + 1) • (x + 1) • (x - 1) • (3x - 5)
Step by step solution :
Step 1 :
Equation at the end of step 1 :
5-(((3•(x2))-2x)•((6-3x2)+2x))
Step 2 :
Equation at the end of step 2 :
5 - ((3x2 - 2x) • (-3x2 + 2x + 6))
Step 3 :
Step 4 :
Pulling out like terms :
4.1 Pull out like factors :
3x2 - 2x = x • (3x - 2)
Trying to factor by splitting the middle term
4.2 Factoring -3x2 + 2x + 6
The first term is, -3x2 its coefficient is -3 .
The middle term is, +2x its coefficient is 2 .
The last term, "the constant", is +6
Step-1 : Multiply the coefficient of the first term by the constant -3 • 6 = -18
Step-2 : Find two factors of -18 whose sum equals the coefficient of the middle term, which is 2 .
-18 + 1 = -17
-9 + 2 = -7
-6 + 3 = -3
-3 + 6 = 3
-2 + 9 = 7
-1 + 18 =
