Question

What value of x will cause the denominator of the following expression to be 0? 4x-9/2x-3. 2/3 3/2 -2/3 -3/2

Answer 1

3/2

Explanation:

4x-9 / 2x-3

From the question, we were told to find the value of x for which the denominator is 0. This implies that:

2x - 3 = 0

Collect like terms

2x = 3

Divide both side by the coefficient of x i.e 2

x = 3/2

Answer 2

3/2 is that value of x

Explanation:

4x - 9/2x - 3

From the above equation, if you substitute 3/2 for x, you have;

4(3/2)-9/ 2(3/2) - 3 then we have;

12/2-9 / 6/2 - 3

6-9/3-3

-3/0 so, by inputting 3/2 for x the denominator is now 0.
