Answer:
-8 (4 x^2 - x + 1)
Step-by-step explanation:
Simplify the following:
3 x (x - 12 x) + 3 x^2 - 2 (x - 2)^2
x - 12 x = -11 x:
3 x×-11 x + 3 x^2 - 2 (x - 2)^2
3 x (-11) x = 3 x^2 (-11):
-11×3 x^2 + 3 x^2 - 2 (x - 2)^2
3 (-11) = -33:
-33 x^2 + 3 x^2 - 2 (x - 2)^2
3 x^2 - 33 x^2 = -30 x^2:
-30 x^2 - 2 (x - 2)^2
(x - 2) (x - 2) = (x) (x) + (x) (-2) + (-2) (x) + (-2) (-2) = x^2 - 2 x - 2 x + 4 = x^2 - 4 x + 4:
-30 x^2 - 2 x^2 - 4 x + 4
-2 (x^2 - 4 x + 4) = -2 x^2 + 8 x - 8:
-2 x^2 + 8 x - 8 - 30 x^2
Grouping like terms, -2 x^2 - 30 x^2 + 8 x - 8 = (-30 x^2 - 2 x^2) + 8 x - 8:
(-30 x^2 - 2 x^2) + 8 x - 8
-30 x^2 - 2 x^2 = -32 x^2:
-32 x^2 + 8 x - 8
Factor -8 out of -32 x^2 + 8 x - 8:
Answer: -8 (4 x^2 - x + 1)
Answer:
In Many Ways
Step-by-step explanation:
Equations help you do complicated problems, they help you prove your thinking, equations can be used in problems which are asked to do with equations(I have lots of those kind.) Equations can help you with Pi too!
A.
b = 16 units and h = 9.6 units
B.
b = 20 units and h = 16 units
C.
b = 20 units and h = 9.6 units
D.
b = 20 units and h = 12 units
Answer: choice D
2x^5 - 6x^3 + 3x^2 - x
Explanation:
Polynomials in standard form always have the exponents decrease (ie go from largest to smallest) when we read from left to right. For choice D, the exponents from left to right are: 5, 3, 2, 1. This is decreasing order. The other answer choices do not have the exponents in decreasing order. The degree of the polynomial in choice D is a 5th degree polynomial since 5 is the largest exponent.
