Question

Fatores .. 10x²-20x²+30x?

Answer 1

10x^2-20x^2+30x
-10x^2+30x=0
delta=b^2-4.a.c
delta=30^2-4.(-10).0
delta=900+0
delta=900
x=-b-/+ raiz de delta/2a
x=-30-30/2.(-10)
x=-60/-20
x=3
x=-30+30/2.(-10)
x=0/-20
x=0

Answer 2

-10X²+30X=0  (-1)
10X² +30X=0
Δ=B²-4AC
Δ=900-4(-10)0
Δ=900
X=-30+OU-√900/-20
X=-30+OU-30/-20
X1=-30-30/20=3
X2=0
