you can't. x=-2 if that equation is true

5x2=10...take 5 two times..5+5=10
No.
There is no rational solution.
5x2 - 136 = 44 5x2 - 136 + 136 = 44 + 136 5x2 = 180 5x2/5 = 180/5 x2 = 36 √x2 = √36 x = ±6
(5x + 13)(x - 3) so x = either -13/5 (ie -2.6) or 3.
5x2-136 = 24 5x2 = 24+136 5x2 = 160 x2 = 32 x = the square root of 32
5x2y = 3x - 6y 5x2y + 6y = 3x y(5x2 + 6) = 3x y = (3x)/(5x2 + 6) This is a rational function.
5x2 = 3 then x2 = 3/5 so that x = sqrt(3/5) = ± 0.7746
I am assuming the question is to factor this problem? 5x2 + 29x - 6 (5x - 1)(x + 6)
1) 5x2-55=90 +55 +55 2) 10x=145 /10 /10 x=14.5
5x2 - 2y2 = -20 7x2 - y2 = 152 Eq1 - 2*Eq2: -9x2 = -324 so that x2 = 36 Substituting the value of x2 in Eq1: 2y2 = 200 so that y2 = 100 The four solutions are (-6, -10), (-6, 10), (6, -10) and (6,10)
