Value of the expression $\frac{20 - (12 + ac)^{2}}{a\times c + 5}$ when a = 2, b = 4, c = -3 is 16 .

Step-by-step explanation:

As the expression given in the question be

$= \frac{20 - (12 + ac)^{2}}{a\times c + 5}$

Where a = 2 , b =4 , c = -3

Putting all the values in the above

$= \frac{20-(12+2\times -3)^{2}}{2\times -3 + 5}$

$= \frac{20-(12-6)^{2}}{-6 + 5}$

$= \frac{20-(6)^{2}}{-6 + 5}$

$= \frac{20-36}{-6 + 5}$

$= \frac{-16}{-1}$

= 16

Therefore the value of the expression $\frac{20 - (12 + ac)^{2}}{a\times c + 5}$ when a = 2, b = 4, c = -3 is 16 .
