(-4x2-5x-1)(4x2-6x-2)
Final result :
-2 • (13x + 1) • (2x2 - 3x - 1)
Reformatting the input :
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 :
(-13x - 1) • ((22x2 - 6x) - 2)
Step 2 :
Pulling out like terms :
3.1 Pull out like factors :
-13x - 1 = -1 • (13x + 1)
Step 3 :
Pulling out like terms :
4.1 Pull out like factors :
(4x2 - 6x - 2) = 2 • (2x2 - 3x - 1)
Trying to factor by splitting the middle term
4.2 Factoring 2x2 - 3x - 1
The first term is, 2x2 its coefficient is 2 .
The middle term is, -3x its coefficient is -3 .
The last term, "the constant", is -1
Step-1 : Multiply the coefficient of the first term by the constant 2 • -1 = -2
Step-2 : Find two factors of -2 whose sum equals the coefficient of the middle term, which is -3 .
-2 + 1 = -1
-1 + 2 = 1
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Step 4 :
Pulling out like terms :
5.1 Pull out like factors :
-26x - 2 = -2 • (13x + 1)
Final result :
-2 • (13x + 1) • (2x2 - 3x - 1)
15 = 0.25x
1500 = 25x
60 = x
The original price was $60.
12x + (-3y) + 4x + (-z)
12 (3) + -3 (13) + 4 (3 ) + (-5)
36 + -39 + 12 + (-5)
36 + 12 -39 - 5
48 - 44

Answer:
i thinks its 11 if its right can i get branilest
Step-by-step explanation:
4+8=12 which is greater than 11
11+8=19 which is greater than 11
11+4=15 which is greater than 11
