Answer:
12a^3-6a^2+2a+9
Step-by-step explanation:
12a^3-6a^2-2a+7+4a+2
12a^3-6a^2+2a+7+2
12a^3-6a^2+2a+9
Step-by-step explanation:
4325 * 32 = 138,400
5492 * 44 = 241,648

Answer:
two real, unequal roots
Step-by-step explanation:
This is a quadratic equation. The quadratic formula can be used to determine how many and what kind of roots may exist:
Find the discriminant, which is defined as b^2 - 4ac, if ax^2 + bx + c = 0. In this case, a = 1, b = -2 and c = -8, so that the discriminant value is
(-2)^2 - 4(1)(-8), or 4 + 32 = 36.
Because the discriminant is real and positive, we know for certain that we have two real, unequal roots
