Solve for aa. Express your answer as an integer or integers or in simplest radical form.
-6-4a^2- -54
To solve for a, we first simplify the expression:
-6 - 4a^2 - (-54)
= -6 - 4a^2 + 54
= 48 - 4a^2
Next step is to set the expression equal to zero:
48 - 4a^2 = 0
Now, we solve for a:
4a^2 = 48
a^2 = 12
a = ±√12
a = ±2√3
Therefore, the solutions for a are a = 2√3 or a = -2√3.
