Question

If x= 9-4.25 find the value of x² +1/x²​

Answer 1

Step-by-step explanation:

Let us go step by step

First let us solve 9-4.25 which is 4.75

Our next step is to substitute the values

so now,

x=4.75

and x2+1/x2 will be

(4.75)2+1/(4.75)2

22.5625+1/22.5625

Now you have to simplify this sum and the answer is 23.5625/22.5625 now let us multiply the terms by 10000 since it is in decimals 23.5625*10000/22.5625*10000=235625/225625 is the expected anser
