Question

4x² -x + 1= x +3x² equação do 2grau ....

Answer 1

4x^2-x+1=x+3x^2
4x^2-3x^2-x-x+1
x^2-2x+1=0
delta=b^2-4ac
delta=(-2)^2-4.1.1
delta=4-4
delta=0
x=-b-/+ raiz de delta/2a
x=-(-2)-0/2.1
x=2-0/2
x=2/2
x=1

Answer 2

4x² -x + 1= x +3x²
4x^2 - 3x^2 - x - x + 1 =
x^2 - 2x + 1 = 0
x = 2 +- 0/2
x' = 1
x" 1

S = {1}
