Answer:
x = 0, x = 1, x = - 3
Step-by-step explanation:
To find the zeros, let f(x) = 0 , that is
(x - 1)(x(x + 1) + 2x) = 0 ← distribute and simplify parenthesis
(x - 1)(x² + x + 2x) = 0
(x - 1)(x² + 3x) = 0 ← factor out x from the second parenthesis
x(x - 1)(x + 3) = 0
Equate each factor to zero and solve for x
x = 0
x - 1 = 0 ⇒ x = 1
x + 3 = 0 ⇒ x = - 3
Answer:
there are no real solutions
Step-by-step explanation:

there is a rule that says

so we have

and we have the definition

so we have

and using the quadratic formula we get that
there are no real solutions
Answer:
1) There are 4 sides in a square where all the sides are equal
2) Squares have 90 degree angles!
a nd three) it has 4 equal angles
Step-by-step explanation:
y = 400 × 0.75
y = 300
300 milligrams = 0.75 hours
x = 3 hours
3(300) = 0.75x
900 = 0.75x
x = 1200
Its alot of long division, but the answer is 217.625.
