Answer:
(2x² + 5x + 2) = (2x + 1)(x +2)
Step-by-step explanation:
Given expression is (2x² + 5x + 2).
We have to factorize the given expression.
(2x²+ 5x + 2) = 2x² + 4x + x + 2
= 2x(x + 2) + 1(x + 2)
= (2x + 1)(x + 2)
So the factored form of the given expression will be (2x + 1)(x + 2).

Answer:
Step-by-step explanation:
Quadratic equation has been given as,
Converting this equation into vertex form,
By comparing this equation with the vertex form of a quadratic equation,
y = (x - h)² + k
Here, (h, k) is the vertex of the parabola.
Vertex of the parabola → x = 3, y = 13
Axis of symmetry → x = 3

Answer:
3:5, because for every 3 ears present in the field, there are 5 legs present
Step-by-step explanation:
A cow has 2 ears and 4 legs.
20 cows have 40 ears and 80 legs.
A farmer has 2 ears and 2 legs.
10 farmers have 20 ears and 20 legs.
20 cows and 10 farmers have 60 ears and 100 legs.
Ratio of ears to legs is
60:100 = 3:5
Answer: 3:5, because for every 3 ears present in the field, there are 5 legs present
