Question

-176=-5a^2+4

Answer 1

To solve for a, we need to isolate a on one side of the equation.

Given equation: -176 = -5a^2 + 4

First, let's subtract 4 from both sides:
-176 - 4 = -5a^2
-180 = -5a^2

Now, divide by -5 to solve for a:
-180 / -5 = a^2
a^2 = 36

Take the square root of both sides to solve for a:
a = ±√36
a = ±6

Therefore, the solutions for a are a = 6 or a = -6.
