Answer:
1
Step-by-step explanation:
3x² +24x = -48
3x² +24x + 48 = 0
x² +8x + 16 = 0
By using cross multiplication,
(x-4)² = 0
Therefore,
x-4 = 0
x = 4 (repeated)
Answer:
Only one real solution
Step-by-step explanation:
[tex]{ \tt{ {3x}^{2} + 24x = - 48}} \\ { \tt{ {3x}^{2} + 24x + 48 = 0 }} \\ { \tt{ {x}^{2} + 8x + 16 = 0}} \\ { \tt{(x + 4) = 0}}
