-7(56 - 12) + 6
-302
Simplify. (4x^2 - 2x) (-3x^2 - 4x^2 +1)
A) -12x^5 - 10x^4 + 8x^3 + 4x^2 -2x
B) -12x^5 -22x^4 - 8x^3 + 4x^2 - 2x
C) 12x^5 - 10x^4 +8x^3 + 4x^2 -2x
D) 12x^5 - 22x^4 - 8x^3 + 4x^2 - 2x
Answer: Is the equation enered correctly?
1. The second term, (-3x^2-4x^2+1) is the same as (-7x^2 + 1)
2. I don't see how the answer could contain an x^5 term. The largest I see from the information is x^4
Step-by-step explanation:
solutions to the quadratic equation x^2+3x-28=0
Answer:
look on the graph
Step-by-step explanation:
the solutions are x = -7 and x=4
Answer:
x = -7 ; x=4
Step-by-step explanation:
The easiest way to solve this would be using the quadratic formula, so let's go ahead with that :)
[tex]x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\x=\frac{-3\pm \sqrt{3^2-4\cdot \:1\cdot \left(-28\right)}}{2\cdot 1}\\x=\frac{-3\pm \sqrt{121} }{2} \\\\x=\frac{-3\pm 11}{2} \\\\x=\frac{-3-11}{2} , x=\frac{-3+11}{2} \\x=-7, x=4[/tex]

Step-by-step explanation:
2(1) + 11 = 13
2(2) + 11 = 15
2(3) + 11 = 17
the 2 is the constant difference between the first 2 terms.
the numbers in brackets are the term number.
you have to multiply the difference with the term number.
then you will have to take that answer and subtract it from the first term number.

2 = 2.27 - m/4
I am so bad at math, lol! ^^ HELP ME PWEASE!
Answer:
m = 1.08
Step-by-step explanation:
Subtract 2.27 from both sides.2 - 2.27 = -m/4
Simplify 2 - 2.27 to -0.27.-0.27 = -m/4
Multiply both sides by 4-0.27 × 4 = -m
Simplify -0.27 × 4 to -1.08.-1.08 = -m
Multiply both sides by -1 (-m is also known as -1)1.08 =m
Answer:
m = 1.08
Step-by-step explanation:
Basically, we can start off by finding the difference between 2 and 2.27(which is 0.27). Then we can see that 0.27 is equal to m/4. Since 0.27*4=1.08, we can see that m=1.08.

The cube of a whole number is 48 more
than the square of the same number.
What is the number?
Answer:
x = 4
Step-by-step explanation:
Let the number = x
x^3 = x^2 + 48
x^3 - x^2 - 48 = 0
The answer is 4, but I have no method of doing this rigorously. I can just show that it is true.
x^3 = 4^3 = 64
x^2 = 4^2 = 16
64 - 48 = 16
