# How do you find the limit of (3x^2-x-10)/(x^2+5x-14) as x approaches 2?
May 30, 2018
$\frac{11}{9}$
#### Explanation:
Observe that
$3 {x}^{2} - x - 10 = \left(3 x + 5\right) \left(x - 2\right)$
${x}^{2} + 5 x - 14 = \left(x + 7\right) \left(x - 2\right)$
So we get
${\lim}_{x \to 2} \frac{3 {x}^{2} - x - 10}{{x}^... |

Definition
A function is an equation between two quantities x and y such that one quantity can be defined in terms of the other quantity.
Example
y = mx + c – eq. 1
Where x and y are two quantities, m is some number, a multiple of x and c is a constant number.
This equation may also be written as:
x = (y – ... |
