Question

determine no conjunto É o conjunto de solução 5x^2 -3x=0

Answer 1

5x²-3x=0
a=5 b=-3 c=0

∆=b²-4ac
∆=(-3)²-4.5.0
∆=9

x=-b±√∆ /2a

x1=-(-3)+√9 /2.5
x1=3+3/10
x1=6/10
x1=3/5

x2=3-3 /10
x2=0

S={0; 3/5}

Answer 2

5x² - 3x = 0

x • (5x - 3) = 0

x= 0

5x - 3 = 0

5x= 0 + 3

5x= 3

x= 3/5

S= ( 0 , 3/5)
