3p2 - 21p + 35 = 0 Then p = [21 +/- sqrt(212 - 4*3*35)]/(2*3) = [21 +/- sqrt(441-420)]/6 = [21 +/- sqrt(21)]/6 = 2.736 and 4.264
6
x2-4x-21 = 0 => x = -3 or x = 7 x2-3x-18 = 0 => x = -3 or x = 6
m = 6
21/3 does.
If: 3x-3 = 7x+21 Then: x = -6
(0, -3), (2, 0), (4 ,3)
y = 6/7x+3 General form of the line equation: 6x -7y+21 = 0
3 x 7 = 21
3 + 3 + 3 + 1 + 11 = 21
0
6 or it equals butterfly with one of the 3's backwards and then the 0 and then the other 3
