If you mean the "x" is multiply, then your answer is 35x9+14x8+56x7−30x2−12x−48

Explanation:

=(5x2+2x+8)(7x7+−6)

=(5x2)(7x7)+(5x2)(−6)+(2x)(7x7)+(2x)(−6)+(8)(7x7)+(8)(−6)

=35x9−30x2+14x8−12x+56x7−48

=35x9+14x8+56x7−30x2−12x−48

Answer:

$\frac { 4 } { 5 }$

Step-by-step explanation:

We are given the following two points and we are to find the slope of the line which passes through these points:

$(3.-1)$ and $(-2,-5)$

The formula of the slope is given by:

Slope = $\frac { y _ 2 - y _ 1 } { x _ 2 - x _ 1 }$

Substituting the given coordinates in the above formula:

Slope = $\frac { - 5 - ( - 1 ) } { - 2 - 3 } = \frac { 4 } { 5 }$

Answer:

(x+3)(x+4)(x-4)

x+2 and x-3 are not factors but x-4 is

Step-by-step explanation:

let's factor it :)

x^3 + 3x^2 - 16x -48

first we will factor this:

x^3 + 3x^2

x^2(x + 3)

then factor the second part :

- 16x - 48

-16(x + 3)

so now,

x^2(x + 3) - 16(x + 3)

factor out x+3

(x+3)(x^2 - 16)

factor x^2 - 16

(x+3)(x+4)(x-4)
