Question

Evaluate x2/y + x2/z for x = 6, y = -4, and z = -2. -27 -9 9 27

Answer 1

Answer:

The value of the given expression is -27.

Given:

$\frac{x^{2}}{y}+\frac{x^{2}}{z}$

Step-by-step explanation:

In this problem, we need to solve the given expression in which we need to find the values of the variables. Since, the values of the variables are given, we can substitute the values and solve the equation as numerical calculation.

On substituting the values,

$\Rightarrow \frac{x^{2}}{y}+\frac{x^{2}}{z}=\frac{(6)^{2}}{-4}+\frac{(6)^{2}}{-2}$

On squaring the values in the numerator,

$\Rightarrow \frac{x^{2}}{y}+\frac{x^{2}}{z}=-\frac{36}{4}-\frac{36}{2}$

On cancelling the numerator and denominator,  

$\Rightarrow \frac{x^{2}}{y}+\frac{x^{2}}{z}=-9-18$

On adding,

$\Rightarrow \frac{x^{2}}{y}+\frac{x^{2}}{z}=-27$
