4 x (в квадрате) +11 х - 3 = 0

Answer 1

$= 4 {x}^{2} + 11x - 3 = 0 \ d = 121 + 48 = 169 \ x1 = frac{ - 11 + 13}{8} = frac{2}{8} = frac{1}{4} = 0.25 \ x2 = frac{ - 11 - 13}{8} = - frac{24}{8} = - 3$

Answer 2

$4x^2+11x-3=0 \ D = 121 + 48 = 169 \ x_{1,2} = frac{-11 pm 13}{8} = left { {{x_1=-3} atop {x_2=0,25}} right.$
