Divide (6a² +5ab - 6b²) by (3a-2b)

The answer is 2a + 3b , the expression that represents the cost of one unit of cellphone.

2a + 3b is also a factor of 6a² +5ab-6b², the other is 3a-2b

Using long algorithm method or synthetic division.

Because of the limitations in the symbols/equation that can be used here, I'll just re-write the given as a rational expression, which is another way to solve the problem especially if you knew how to factor polynomials.

__6a² + 5ab - 6b²__

3a - 2b

=__(3a-2b) (2a + 3b) __ Factor the numerator (also the dividend)

3a - 2b

= 2a + 3b

The answer is 2a + 3b , the expression that represents the cost of one unit of cellphone.

2a + 3b is also a factor of 6a² +5ab-6b², the other is 3a-2b

Using long algorithm method or synthetic division.

Because of the limitations in the symbols/equation that can be used here, I'll just re-write the given as a rational expression, which is another way to solve the problem especially if you knew how to factor polynomials.

3a - 2b

=

3a - 2b

= 2a + 3b
