Answer:
12x⁴ - 15x³ + 18x²
Step-by-step explanation:
1. distribute -3x²
-3x² • 5x = -15x³
-3x² • -4x² = 12x⁴
-3x² • -6 = 18x²
2. combine terms and put in descending order (standard form)
12x⁴ - 15x³ + 18x²
Quadratic trinomals are in the form of x^2+bx+c
You need to find the factors of c that add up to b.
So the first question x^2+5x-14
You are looking for the factors (multiply) of -14 that add up to 5
You need to do the same for the next one. Factors of 3 that add up to -4
Those factors would be -3 and -1
That makes the factors (x-1)(x-3)
<span>The goal in simplifying numbers
is to reduce it that can be best seen in the eye. Also in
converting units, you must take note of the units given in the problem. If you
don’t, you would get a lot of errors. Length is the measure of distance and can
be best represented by either in SI units or English units. Example of an SI unit is meter, m, and English
unit is feet, ft. You are given 3 inches and 2 feet. You can convert any of the
numbers into a number that would feel comfortable to you. I will take 3 inches.
Note that there are 12 inches in 1 feet. So divide 3 by 12 and you will get ¼ feet.
Then divide 2 feet to ¼ feet and you will get 8.</span>
Semiannual means there will be two total periods in a year. Divide ten percent by two to get the interest rate per period. Then multiple by 1+i twice
Answer:
The Three expressions that have a sum or difference of 3 /4 .
B . 11/12 − 1/6
C. 3/5 + 3/20
E . 2/3 + 1/12
Step-by-step explanation:
The Three expressions that have a sum or difference of 3 /4 .
are
B . 11/12 − 1/6
Therefore,
C. 3/5 + 3/20
Therefore,
E . 2/3 + 1/12
Therefore,
