To determine

To calculate: The common factor of the expression 30x3+15x4 .

Expert Solution

Answer to Problem 96E

The common factor of the expression 30x3+15x4 is 15x3(x+2) .

Explanation of Solution

Given information:

The expression 30x3+15x4 .

Formula used:

To factor out the common factor from a polynomial, find out the greatest common factor and express the polynomial as a product of the simpler ones.

Calculation:

Consider the given expression 30x3+15x4 .

Recall that to factor out the common factor from a polynomial, find out the greatest common factor and express the polynomial as a product of the simpler ones.

Here, the greatest common factor of the terms 30x3 and 15x4 is 15x3 ,

So, 30x3+15x4 can be written in simplified form as,

  30x3+15x4=15x3(2+x)=15x3(x+2)

Thus, the common factor of the expression 30x3+15x4 is 15x3(x+2) .
