Question

Qual é o resultado de 5x² – X + 6x² – 3x?

Answer 1

5x² -x +6x² -3x
5x² +6x -3x -x
11x² -4x

11x² -4x +0
Δ= b²-4ac
Δ= (-4)² -4.11.0
Δ= 16

x= -b +/- √Δ /2a
x= 4 +/- √16 / 2.1
x'= 4 +4/2
x'= 8/2
x'=4

x''= 4 -4/2
x''= 0/2
x''= 0

Bons estudos!

Answer 2

5x^2 -x +6x^2 -3x
11x^2 -4x

delta= b^2 -4ac
16 -4.11.0
delta=16

x= -b +-raiz de delta/2a
+4 +-4 /22
8/22 0/22
8/22 = 4/11

x igual a 0 e 4/11
