Question

if a minus 1 by a is equal to 5 find the value of a square + 1 by square - 3a + 3 by a​

Answer 1

Answer:

26

Step by step explanation:

I think you meant the question to be like that in the picture given above.

Note that, I marked each block with numbers 1, 2, 3, and 4 to go through the answers in order.

In the 1st block we get,

$a = \frac{ - 1}{4}$

In the 2nd block we get,

$\frac{ {a}^{2} + 1}{ {a}^{2} } = 17$

In the 3rd block we get,

$\frac{3a + 3}{a} = - 9$

And, in the 4th block we get,

$( \frac{ {a}^{2} + 1 }{ {a}^{2} } ) - ( \frac{3a + 3}{a} ) = 17 - ( - 9) = 17 + 9 = 26$

So, the answer is 26.
