Hi,
Pretty simple: if a result of a multiplication is equal to 0, then each factor is equal to 0.
y = f(x) = (x -- 5)(x + 2)² = 0, so:
x₁ -- 5 = 0 ⇒ x₁ = 5.
(x + 2)² = 0 ⇒ x₂ = x₃ = --2, for --2 we have state of multiplicity = 2.

Answer:
Step-by-step explanation:
The graph of 
in vertex form is 
where h and k, the vertex, is (0, 0). If we shift the parabola right or left, or up or down, the h and k values take on that reflection. If we move up 4, k goes from a value of 0 to a value of 4; if we move right 2 units, h goes from a value of 0 to a value of 2. Putting that together in work (aka vertex) form:
Answer:
x = -35/22, or 1.5909090...
Step-by-step explanation:
Solving for x will be easy enough, but cross multiplication won't be necessary as that's only applicable when division is involved:
35 = 2x - 24x
35 = -22x
x = -35/22, or 1.5909090...
Should be 11 and 6 because when you add 11 and 6 you get 17 and when you subtract them you get 5
