262.5=10.5x+24x
How can I solve this?

x=7.608696

Step-by-step explanation:

Simplify both sides of the equation.

262.5=10.5x+24x

262.5=(10.5x+24x)(Combine Like Terms)

262.5=34.5x

262.5=34.5x

Step 2: Flip the equation.

34.5x=262.5

Step 3: Divide both sides by 34.5.

34.5x

34.5

=

262.5

34.5

x=7.608696

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
