Question

G= - X2 + 4X -3 RESOLVA AS QUESTAO

Answer 1

x2 + 4x - 3 = 0

delta = b^2 - 4.a.c

delta = 4^2 - 4*1*(-3)

delta = 16 -12

delta = 4

x1 = (-b + raiz(delta)) / 2 * a

x2 = (-b - raiz(delta)) / 2 * a

x1 = (- 4 + 2) / 2

x1 = -2/2

x1 = - 1

x2 = (- 4 - 2) / 2

x2 = - 6 / 2

x2 = - 3

G1 = -1 ^ 2 + 4*(-1) - 3

G1 = 1 - 4 - 3

G1= 1 - 7

G1 = - 6

G2 = -3 ^ 2 + 4*(-3) - 3

G2 = 9 - 12 - 3

G2= 9 - 15

G2 = - 6
