Discriminant = b^2 - 4ac, where a, b and c come from the form of the quadratic equation as ax^2 + bx + c
Discriminant = (4)^2 - 4(1)(5)
= 16 - 20
= -4
-4 < 0, therefor there are no roots
(If the discriminant = 0, then there is one root
If the discriminant > 0, there are two roots, and if it is a perfect square (eg. 4, 9, 16, etc.) then there are two rational roots
If the discriminant < 0, there are no roots)
Answer:
true
Step-by-step explanation:
not 100% sure but I had a question similar a few years back.
Answer:
117,649a^8c^2
Step-by-step explanation:
(7^3 a^4 c) ^2
= 7^(3*2) a^(4*2) c^2
= 7^6a^8c^2
= 117,649a^8c^2
