Question 598581
Hi, there--
.
You want to evaluate the rational expression for x=-3. Substitute -3 for x and simplify.
.
{{{(3x^2+x-4)/(2x^2+3x-4)}}}
{{{(3(-3)^2+(-3)-4)/(2(-3)^2+3(-3)-4)}}}
{{{(3(9)-3-4)/(2(9)-9-4)}}}
{{{(27-7)/(18-13)}}}
{{{20/5}}}
{{{4}}}
.
When x = -3, the expression evaluates as 4.
.
I got a different answer than you did. It's possible that I am using the wrong equation. Check that carefully, before you change your answer. If you still have questions, feel free to email me via gmail.
