True or false the expression below is a sum of cubes 216x^3+64?

True

Step-by-step explanation:

The sum of cubes   a^ 3 + b^ 3 = (a + b) (a ^2 − a b + b^ 2 )

We need to determine if 216x^3 is a cube and 64 is a cube

216 = 6*6*6

216 x^3 = (6x) ^3

and 64 = 4*4*4 = 4^3

So 216x^3 +64 = (6x)^3 + 4^3

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
