Find the discriminant of 3x^2-10x =-3

64

Step-by-step explanation:

We need to get the equation in the form

ax^2 +bx+c =0

3x^2-10x =-3

Add 3 to each side

3x^2-10x+3 =-3+3

3x^2-10x+3 =0

a=3   b = -10  c = 3

The discriminant  is

b^2 - 4ac

(-10)^2 - 4(3)(3)

100 - 36

64

well

44-3-3-3=35

35+4+4+4+4=51

so the ansewr would be 51 degreesat 7: 00

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
