Step-by-step explanation:
±4i, ±3
p(x) = A(x - 4i)(x + 4i)(x - 3)(x + 3), with A = 1.
Answer:
The total volume is 375
Step-by-step explanation:
To find volume you take Length x Width x Height. 5 x 5 x 5 = 125. 125 x 3.
Answer:
1. 6x^2 + 4x - 4y
2. x - 10y.
3. 6x^5
4. 36 a^6 b^8
5. x^2 - 81
6. 9x^2 - 42x + 49
7. 12x^2 +3x - 42
Step-by-step explanation:
1. 3x^2+4x+3x^2-4y
Add the like terms, we get
6x^2 + 4x - 4y
2. (5x-2y)-(4x+8y)
Now distribute the negative sign, we get
5x - 2y -4x -8y
Simplify the like terms, we get
x - 10y.
3. 3x^3(2x)^2
Multiply the numbers and simplify the variables
6x^(3 +2)
6x^5
4. (-6a^3b^4)^2
Now bring the power 2 inside the parenthesis.
-6^2 a^6 b^8
= 36a^6b^8
5. (x+9) (x-9)
x^2 + 9x -9x - 81
x^2 - 81
6. (3x-7)^2
(3x - 7)(3x - 7)
9x^2 - 21x -21x + 49
9x^2 - 42x + 49
7. (3x+6) (4x-7)
12x^2 + 24x -21x - 42
12x^2 +3x - 42
Thank you.
Answer:
<em><u>-2/3</u></em>
Step-by-step explanation:
To find slope, you do the first point's y-value minus the second point's y-value, than divide that by the first point's x-value minus the second point's x-value.
(4 - 2)/(-3 - 0)
2/-3
-2/3
(2x+2)(x+2) Look there is a way most people don't know but I always use it. it's super easy once you learn it. So the equation is ax²+bx+c=0 b you have to think of two numbers whose sum is b and prod. is ac. So in this situation the sum is 6 and the prod. is 2×4=8 . Two numbers there sum is 6 and product is 8 are: 4 and 2 so we rewrite the equation 2x²+6x+4 delete the 6x and put the two numbers we found with an x like this : 2x²+4x+2x+4 then you take the first two together and the last two together like this : (2x²+4x)+(2x+4) you then factorise the two brackets take the common factor. 2x(x+2)+2(x+2) In any equation it's a must to find two similar brackets take them common and combine like this (x+2)(2x+2). and then it's done. I know it's a bit strange and hard but once you perfect it any polynomial is a piece of cake.
