Multiply. (X – 5) (X – 1) (X + 5)?

Question

Multiply. (X – 5) (X – 1) (X + 5)

Answer 1

(x^2-25)(x-1)=x^3-x^2-25x+25

Answer 2

multiply (x - 5) (x + 5) first,

(x^2 - 25) ( x - 1)

x^3 - x^2 - 25x + 25

Answer 3

Simplifying
(x + -5)(x + -1)(x + 5)

Reorder the terms:
(-5 + x)(x + -1)(x + 5)

Reorder the terms:
(-5 + x)(-1 + x)(x + 5)

Reorder the terms:
(-5 + x)(-1 + x)(5 + x)

Multiply (-5 + x) * (-1 + x)
(-5(-1 + x) + x(-1 + x))(5 + x)
((-1 * -5 + x * -5) + x(-1 + x))(5 + x)
((5 + -5x) + x(-1 + x))(5 + x)
(5 + -5x + (-1 * x + x * x))(5 + x)
(5 + -5x + (-1x + x^2))(5 + x)

Combine like terms: -5x + -1x = -6x
(5 + -6x + x^2)(5 + x)

Multiply (5 + -6x + x2) * (5 + x)
(5(5 + x) + -6x * (5 + x) + x^2(5 + x))
((5 * 5 + x * 5) + -6x * (5 + x) + x^2(5 + x))
((25 + 5x) + -6x * (5 + x) + x2(5 + x))
(25 + 5x + (5 * -6x + x * -6x) + x^2(5 + x))
(25 + 5x + (-30x + -6x^2) + x^2(5 + x))
(25 + 5x + -30x + -6x^2 + (5 * x^2 + x * x^2))
(25 + 5x + -30x + -6x2 + (5x^2 + x^3))

Combine like terms: 5x + -30x = -25x
(25 + -25x + -6x^2 + 5x^2 + x^3)

Combine like terms: -6x^2 + 5x^2 = -1x^2
(25 + -25x + -1x^2 + x^3)

Answer 4

x/(x+1) - 5/(x-2)=1 make the denominator common for all terms on the left to get x(x-2)/(x-2)(x+1)-5(x+1)/(x+1)(x-2)=1 multiply (x^2 -2x)/(x-2)(x+1) - (5x+5)/(x+1)(x-2)=1 add the terms with like denominators (x^2 -2x -5x -5)/(x+1)(x-2)=1 multiply both sides by (x+1)(x-2) x^2-2x-5x-5=(x+1)(x-2) expand the right side x^2-7x-5=x^2-x-2 simplify x^2-x^2 -6x =5-2 simplify -6x=3, then x = 3/-6 = -1/2 Check your answer by substituting -1/2 for x and solve -1/2/(1/2) - 5/(-5/2) =-1+2 = 1

Answer 5

(x - 5) (x + 5) (x - 1) =
(x^2 - 25)(x - 1) =
x^3 - x^2 - 25x + 25

Answer 6

x^3 - x^2 - 25x + 25

Answer 7

x^3 - x^2 - 25x + 25

Answer 8

the answer is

X3-X2-25X+25
read as X cubed minus X spuared minus twenty-five X plus twenty-five

it isn't hard to do

Answer 9

-25. The x's cancel out.
