Finding the product of these->

I need help finding the product of these. 6x^2(x^4-2) and 8x^2y^3(xy^2-4x+7y) If anyone can help with these they will get *Best Answer. Thank you :D-6x^6 - 12x^2 8x^3y^5 - 32x^3y^3 + 56x^2y^4-1.6

Function with zeros 2, -3/2, and -1. Give an equation for the polynomial function.

f(x) =a( x- 2)( x-3/2)(x +1)= a/2 (x-2)(2x-3)(x+1)= a/2 (x-2) ( 2x^2 -x -3)= a/2 ( 2x^3 -x^2 -3x -4x^2 +2x +6)= a/2 ( 2x^3 - 5x^2 -x +6)= ax^3-5a/2 x^2-a/2 x +3a where a is a real number. This repres

Can you please explain how to differentiate y=ln(5xxx-2xx+1)

You would simply use the chain rule. Moreover dy/dx (ln u)=[1/u][du/dx] dy...........1 —..=..—————— times15x² - 4x dx.......5x³ -2x² + 1 we can write that as one rational expression dy........1

Slope Intercept form equation help.

1. What is the slope -intercept form of the equation of the line (1, -1) , m = - 6/5 .--1=(-6/5)(1)+b Solve for b... Plug b and the m into the slope-intercept form-The general eq. is y=mx+c, where m

Partial Fraction Decomposition (9x+1)/(X^3 + x^2)

Id be very grateful if someone could help me with this problem. My math book does a horrific job of explaining this partial fraction decomposition stuff. Thanks a million!-(9x + 1)/(x^3 + x²) = (9x +

Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this. x + 8y = 14 -3x + 4y = 0-3x + 24y = 42 -3x + 4y = 0---------ADD 28y

Rewrite log(cubed root of 34) as a product.

I understand that the square root is equal to x^1/2. But what is the cubed root equal to?-The cube root is x^1/3 so log(cube root of 34) would also be: 1/3 log(34)-x^(m/n) = n_√x^m ---- where n_√ is t

Find the domain, range and roots (that is, where y=0) of the function

y = -x^3+x^2+x-1 Please show your working. Thankyou -Domain is all real numbers and so is the range. Certainly x = 1 is a root. x= -1 is also a root. The function factors as -(x-1)^2*(x+1). This is

Probability question and the word at least

I know when there is at least you could add up it and all the combinations above it, but my teacher said there was a shortcut. Here is the question: An icecream vendor sells 15 flavors of icecream. Y

People rely to much on calculators

people need to think with their heads. hear i explain what 2^x=10. you must not use log rithems to solve but you must use your mind. the answer is 3.625, and other people say its 3.321.my answer is ri

Expand and simplify sin(θ + π/3) ?/

sin(θ + π/3) = sinθ cos π/3 + cosθ + sin π/3 = sinθ (1/2) + cosθ (√3/2) = 1/2(sinθ + √3cosθ)-sin(θ + π/3) = sinθcosπ/3 + cosθsinπ/3 = 1/2.sinθ + √3/2.cosθ
