Question

URGENTEEE RESOLVA A EQUAÇÃO USANDO BASKARA -3X²+10X-3=

Answer 1

Explicação passo-a-passo:

delta = b^2 - 4ac

delta = 100 - 36

delta = 64

$\frac{ - b \: + - \sqrt{delta} }{2a}$

$\frac{ - 10 + - 8}{ - 6}$

x1 (+) = 1/3

x2 (-) = 3

Answer 2

Explicação passo-a-passo:

a= -3

b= 10

c= -3

$b^{2}-4.a.c\\10^2-4.(-3).(-3)\\100-36\\64\\x=\frac{-b\pm\sqrt{x} }{2.a}\\\\x=\frac{-10\pm 8}{-6}\\x_1=\frac{-10-8}{-6}\\x_1=\frac{18}{6}\\x_1= 3\\\\x_2= \frac{-10+8}{-6}\\x_2= \frac{-2}{-6}\\x_2=\frac{1}{3}$
