What is the product of -2x^3 + x - 5 and x^3 - 3x - 4
Show your work

(-2x³ + x - 5) (x³- 3x - 4)

- 2x⁶ +6x⁴ + 8x³ + x⁴ - 3x² - 4x -5x³ + 15x + 20

Combine like terms

Answer #1       -2x⁶ + 7x⁴ + 3x³ - 3x² + 11x + 20

Step-by-step explanation:

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
