Solve this equation with steps: 8x³-125=0
You must use differences of squares to get the answer.

Answer

2.0

Step-by-step explanation:

x2+8x+15=0

x2+8x=-15

x2-8x+(8x1/2)2=-15+(8x92)

(X-8/2)2=-15+64/4

(x-8/2)2=4/4

take the square root of both sides

X-8/2=v4/4

X-8/2+2/2

x=8/2+2/2 or 8/2-2/2

x=10/2 or 6/2

x=5 or 3 an

Step-by-step explanation:

The given is the equation of degree 3 so no differences of squares applicable

The solution is:

It has one real root only

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
