Question

6x2+7x-3=0
Пожалуйстааа :'(

Answer 1

d=49-4*6*(-3)=49+72=121
x1=(-7-11)/12=3/2=1,5
x2= (-7+11)/12=1/3

Answer 2

$6 x^{2} + 7 x - 3 = 0$

$a=6 ; b=7; c= -3$

$D= b^{2} - 4ac$

$D= 7^{2} - 4*6*(-3) = 49+72=121$

$x_{1} = frac{-b+ sqrt{D} }{2a}$

$x_{2} = frac{-b- sqrt{D} }{2a}$

$x_{1} = frac{-7+11}{12} = frac{4}{12} = frac{1}{3}$

$x_{2} = frac{-7-11}{12} = frac{-18}{12} = -frac{3}{2} = -1 frac{1}{2}$
