Step-by-step explanation:
Generally speaking, the number of solutions to an algebraic equation is equal to the exponent of the highest power. so the answer is b.4
Answer:
Exactly two distinct zeros
Step-by-step explanation:
y = 2(x-1) (x + 4)
Plug y = 0
0 = 2(x-1) (x + 4)
0/2 = (x-1) (x + 4)
(x-1) (x + 4) = 0
(x-1) = 0 or (x + 4)= 0
x = 1 or x = - 4
Here, x has two distinct roots, therefore given quadratic relation has Exactly two distinct zeros.
