24x+39d-18 how to factor

24x + 39d - 18

= 3 (8x + 12d - 6) or - 3 (-8x - 12d + 6)

X = - b ± b 2 - 4 a c 2 aWhere a = 24, b=39, and c=-18

Applying values to the variables of quadratic equation - b, a and c we have

d = - 39 ± 39 2 - 4x 24x - 18 2x 24This gives

d = - 39 ± 39 2 - - 1728 48d = - 39 ± 3249 48

d = - 39 ± 57 48

d1 = - 39 + 57 48

d2 = - 39 - 57 48

d 1 = 18 48

d 1 = - 96 48

The d values are

d1 = 0.375 and d2 = - 2
