Answer:
2
Step-by-step explanation:
y = 0 at the point where the function intersects x-axis. Thus, yiou have to put
2x2 + x - 10 = 0
and solve the equation. It is better to factor the quadratic expression, which gives us
2x2 + x - 10 = (2x+5)(x-2) = 0
We have 2x +5 = 0 and x-2 = 0. Thus, the intercepts are x = -5/2 = - 2.5 and x = 2.

The area of the square increasing at 30 
The rate of change function is defined as the rate at which one quantity is changing with respect to another quantity. In simple terms, in the rate of change, the amount of change in one item is divided by the corresponding amount of change in another
Let the side of a square be x.
So,
Area of square = 
A =
Differentiating with respect to time we get,
dA/dt = 2x dx/dt
When area = 9
the side becomes 3 cm
At x = 3cm and dx/dt = 5 cm/s (Given)
dA/dt = 2.3.5 = 30 
Thus the area of the square increasing at 30
