To find the value of a^2 + 8a + 8, we can use the quadratic formula or factorization.
Let's use the quadratic formula:
a^2 + 8a + 8 = 0
Using the quadratic formula, we have:
a = (-8 ± √(8^2 - 4*1*8))/(2*1)
a = (-8 ± √(64 - 32))/(2)
a = (-8 ± √32)/(2)
a = (-8 ± 4√2)/(2)
Simplifying further, we have:
a = -4 ± 2√2
Therefore, a^2 + 8a + 8 = (a + 4 + 2√2)(a + 4 - 2√2)
a^2 + 8a + 8 = ?
