y=((square root of 2)+1) [tex]c = 2.2403703492[/tex] [tex]e = 5.71307488659[/tex]
1) (y-1)^2 =2 so we can concludes that y-1 = squareroot of 2 so ((squareeroot of 2+1) - 1)^2 = 2
2)First we can convert 21÷2 fraction to decmial form which is 10.5 so our equation would be (c+1)^2= 10.5 so c+1 is the sqaureroot root of 10.5 so c would be the (square root of 10.5)-1
3)We can again convert those fractions to decimals so 3/2=1.5 and 71/4 =17.75 so our equation would be (e-1.5)^2=17.75 so (e-1.5) is the square root of 17.75 so e=((square root of 17.75)+1)
