Use the factors here to decompose the following cubes as much as possible:

F(x)=x (cube of) -7x+6

2

Find a given factor that (x+4) is f (x) = cube of x () +8x+ax+ 12, and then the fact rises completely by f (x).

three

Prove that (x-2) is a factor of the cube of f(x)= x-4x+x+6, and then solve f (x) = 0.

four

Find three solutions to each of the following equations.

10x cubic -29x+25x-6 = 0.

five

The expression ax+bx+6 has a remainder 15 when divided by (x- 1) and a remainder 1 when divided by (x+ 1). Find the values of a and b.

Answer:

-5/2(a-3) divided by 16/a-3+(a+3)

A-5/2(a-3) divided by 16/a-3+(a+3)(a-3)/(a-3)

A-5/2(a-3) divided by (16+A 2-9)/(A-3)

A-5/2(a-3) divided by (7+A 2)/(A-3)

A-5/2(a-3)) times (A-3)/(7+A 2)
