Solve:
-9x^2 − 9 = 3(5x^2 − 3)
RHS = 15x^2 − 9, so
-9x^2 − 9 = 15x^2 − 9
Add 9 to both sides:
-9x^2 = 15x^2
⇒ -24x^2 = 0
⇒ x^2 = 0 ⇒ x = 0.
There is 1 unique real solution (x = 0).
-9x^2 − 9 = 3(5x^2 − 3)
RHS = 15x^2 − 9, so
-9x^2 − 9 = 15x^2 − 9
Add 9 to both sides:
-9x^2 = 15x^2
⇒ -24x^2 = 0
⇒ x^2 = 0 ⇒ x = 0.
There is 1 unique real solution (x = 0).
