Question

Calculate -
for x = 2
(x+5) (x - 5)
__________
x² +5​

Answer 1

Answer:

$\frac{(x + 5)(x - 5)}{ {x}^{2} + 5 } \\ given \: that \: x = 2 \\ = \frac{(2 + 5)(2 - 5)}{ {2}^{2} + 5 } \\ = \frac{7( - 3)}{4 + 5} \\ = \frac{ - 21}{9} \\ = \frac{ - 7}{3}$

Answer 2

Answer:

-7/3

Step-by-step explanation:

(x+3)(x-3)/x²+5

(2+5)(2-5)/2²+5

7×-3/4+5

-21/9 (divide by 3)

-7/3
