Question

ajuda na equacao 3x² = 2

e 3x² + 7 = 0

Answer 1

3x²=2
3x²-2=0

a = 3
b = 0
c = -2

x = (-b ± √∆)/2a
∆ = b² - 4 * a * c
∆ = 0² - 4 * 3 * -2
∆ = 24
x = (-(0) ± √24)/23
x = 0 ± 4.898979485566356/6
x1 = 0 - 4.898979485566356/6 = -0.8164965809277259
x2 = 0 + 4.898979485566356/6 = 0.8164965809277259



a = 3
b = 0
c = 7

x = (-b ± √∆)/2a
∆ = b² - 4 * a * c
∆ = 0² - 4 * 3 * 7
∆ = -84
nao tem solucao em IR
