Question

please help me with x=(-3±√(3^2-4(6)(-18)))/(2(6))
I got as far as x= -3±√441/12 but then get stuck there

Answer 1

the square root of 441 is 21

Answer 2

the square root of 441 is 21

so we have

x = (-3 +21)/12 = 3/2

and

x = (-3 -21)/12 = -2

Answer 3

you were almost there

Answer 4

I get confused on the first x = (-3+21)/12 because its a fraction

Answer 5

I end up with x = 18/12 but then what

Answer 6

reduce by 6

Answer 7

-3 + 21 = 18

so we have 18/12

18 and 12 are divisible by 6

18 divided by 6 = 3
12 divided by 6 = 2

so we have

18/12 = 3/2
