Question

Oi vcs podem me ajudar e na formula bhaskara (a) 6x²+x-1=0 (b) 3X²-7X+2=0

Answer 1

A) 6x²+x-1=0

Δ=1²-4.6.-1
Δ=1+24
Δ=25

x=$\frac{-1+-√25}{2.1}$
x=$\frac{-1+-5}{2}$

x¹=$\frac{-1-5}{2}$
x¹=$\frac{-6}{2}$
x¹=-3

x²=$\frac{-1+5}{2}$
x²=$\frac{4}{2}$
x²=2


B) 3x²-7x+2=0

Δ=-7²-4.3.2
Δ=49-24
Δ=25

x=$\frac{7+-√25}{2.3}$
x=$\frac{7+-5}{6}$

x¹=$\frac{7-5}{6}$
x¹=$\frac{2}{6}$

x²=$\frac{7+5}{6}$
x²=$\frac{12}{6}$
x²=2
