5x^(2) = 11
Divide both saudes by 5'
Hence
x^(2) = 11/5
Square root both sides
x = +/-sqrt (11/5)
Or x = +/-sqrt(2.2)
This would normally by left in 'surd' form, because the answer is an IRRATIONAL number; the decimals go to inifinity!!!!!
However, per calculator
x = +/- 1.483239697.....
5x2 = 3 then x2 = 3/5 so that x = sqrt(3/5) = ± 0.7746
1) 5x2-55=90 +55 +55 2) 10x=145 /10 /10 x=14.5
-5x2 = -75 x2 = 25 x = ±sqrt( 25 ) x = ±___
X= (3/5 , -2)
5x2=8x Divide with x on both sides5x= 8 Solve xx=8/5

5x2-8x-4
x2 • (5x2 + x + 8)
5x2-2x = 0 x(5x-2) = 0 Therefore: x = 0 or x = 2/5
h = +11 and/or -11
5x2=10...take 5 two times..5+5=10
No.
5x2 - 136 = 44 5x2 - 136 + 136 = 44 + 136 5x2 = 180 5x2/5 = 180/5 x2 = 36 √x2 = √36 x = ±6
