In disguise In standard form a, b and c x2 = 3x -1 x2 - 3x + 1 = 0 a=1, b=-3, c=1 2(x2 - 2x) = 5 2x2 - 4x - 5 = 0 a=2, b=-4, c=-5 x(x-1) = 3 x2 - x - 3 = 0 a=1, b=-1, c=-3 5 + 1/x - 1/x2 = 0 5x2 + x - 1 = 0 a=5, b=1, c=-1 .

equation. Solution: Here we have : $ a = 2 b = 7 c = -15 $ $$x{1,2} = frac{ -b pm sqrt{b^2-4 a c} }{2a}$$ $$x{1,2} = frac{ -7 pm sqrt{7^2 - 4cdot 2cdot(-15)}}{2cdot2}$$ $$x{1,2} = frac{ -7 pm sqrt{49 + 120}} {4}$$ $$x{1,2} = frac{ -7 pm sqrt{169}} {4}$$ $$x{1,2} = frac{ -7 pm 13} {4}$$ To calculate first solution we use "+" sign: To calculate second solution we use "-" sign: $$x{1} = frac{-7 + 13} {4}$$ $$x{1} = frac{6}{4}$$ $$x{1} = frac{3}{2}$$ $$x{2} = frac{-7 - 13} {4}$$ $$x{2} = frac{-20} {4}$$ $$x{2} = -5$$ Exercise: Solve equation 3x2 + 2x - 5 = 0.
