16-36+ 91/4=25-45+91/4,ie (4-9/2)(4-9/2)=(5-9/2)(5-9/2),4-9/2=5-9/2ie4=5where the maths has gone wrong?

Update:

I am sorry In the question it should be 81/4 and not 91/4 wherever 91/4 comes and on suqare rooting the final of test will get you 4=5 so where the maths has gone wrong

    16-36+ 91/4=25-45+91/4

    -20+81/4=-20+81/4

    .25=.25

    (4-9/2)(4-9/2)=(5-9/2)(5-9/2)

    (-.5)^2=.5^2

    .25=.25

    Yes, strange as it looks

    4-9/2=-.5

    5-9/2=.5

    both square to .25

  • Won't do your work for you, but both work out ok. Try subtracting 91/4 from both sides of the first equation, and remember in the second equation that two negatives times each other is a positive.

    IPL1 Rajastan Royals received -12 suits Shane Watson - 4 guy of the tournament Sohail Tanvir - 2 mom So the gamers to blame for 0.5 their wins in 2008 isn't interior the crew..Rajastan bypass over those tournament triumphing gamers....also lack of kind of last key gamers..except Yusuf Pathan for sure..who replaced into fab very last time round too..mom in 3 video games of the 6 they received in 2009 version..yet there's a decrease to which one participant can make a contribution....Smith, Warne not in good kind...loved ones gamers r not experienced sufficient...also in some unspecified time sooner or later they'd even bypass over jadeja too even although he lost many suits for them very last time with the bat..In bowling circumstances like in India they choose him..he has been performing continuously nicely as a bowler for India in 50 over format

    16-36+91/4=25-45+91/4

    (-20+91)/4=(-20+91)/4

    (-80+91)/4=(-80+91)/4

    11/4=11/4

    (4-9/2)(4-9/2)=(5-9/2)(5-9/2)

    -1/2=-1/2

    16-36+91/4=25-45+91/4

    -20+22,75=-20+22,75

    2,75=2.75

    (4-9/2)(4-9/2)=(5-9/2)(5-9/2)

    (4-4,5)(4-4.5)=(5-4.5)(5-4.5)

    0.5*0.5=0.5*0.5

    0.25=0.25
