5x2 = 3 then x2 = 3/5 so that x = sqrt(3/5) = ± 0.7746
X= (3/5 , -2)
1) 5x2-55=90 +55 +55 2) 10x=145 /10 /10 x=14.5
10 + 14x - 3 is pretty much the same thing as 7 + 14x. You can't solve this problem without knowing what x is or what the equation equals out to. For example, if 10 + 14x - 3 = 21, x would equal 1.
-5x2 = -75 x2 = 25 x = ±sqrt( 25 ) x = ±___
5x2=8x Divide with x on both sides5x= 8 Solve xx=8/5
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.....
5x^(2) + 15x = 0 Factor Factor our '5x' Hence 5x(x - 3) = 0 Hence it follows that 5x = 0 Therefore x = 0 or the other multiplicand x - 3 = 0 x = 3 So the answer is x = 0 or x = 3 (two answers).

5x2-8x-4
x2 • (5x2 + x + 8)
5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
In one word 'NO' Since it is and 'x^(2)' term, this will make a parabolic curve, not linear (straight line).
5x2-2x = 0 x(5x-2) = 0 Therefore: x = 0 or x = 2/5
