Question

Resolva com a forma de baskara

3x2²-7x+2=0
Sendo A=3 B=7 C=2

4x²-3x=6x-4
Sendo A=1 B=6 C=8

X(x+1)²=4x+4 sendo A =1 B=2 C=-3

(X+1)²=4x+4 sendo A= B=-2 C=-3

Por favor

Answer 1

3^2-7x+2=0
Baskara
Δ= b^2 -4 .a.c
A=3 , B= -7, C= 2
Δ=-7^2 - 4.3.2
Δ= 49-24
Δ=25
Segunda formula de Baskara
x´= -b +-√Δ / 2.a
x´ =-(-7)+-√25 /2.3
x´= +7 +- 5 /6
x´= +7+5 /6 = 12 / 6=2
x´´=+7 - 5 / 6 = 2/6 = 1/3

2)Exercicio
A=1 , B=6 , C= 8
Baskara = Δ =b^2 - 4 .a.c
Δ=6^2 -4 .1.8
Δ= 36-40
Δ= -4 nâo existe raiz  ∉

3) Exercicio
A=1, B= 2, C= -3
Baskara
Δ=b^2 - 4.a.c
Δ=2^2 -4 .1.(-3)
Δ=4+12
Δ=16
Segunda formula de Baskara
x´= -b+-√Δ /2 .a
x´=-2 +-√16 / 2.1
x´= -2 +- 4/ 2
x´= -2+4/2 = 2/2 =1
x´´ =-2-4 /2 = -6/2 =-3

4) Exercicio
A= , B= -2 ,C=-3
Baskara
Δ=b^2 -4 .a.c
Δ=-2^2 -4.0.(-3)
Δ= 4-0
Δ=4
Segunda formula de Baskara
x´= -b +-√ Δ / 2.a
x´=- (-2)+-√4 /2.0
x´= +2+-2 /0

X´= 0 e X´´ =0
