The correct answer would be =
It is somewhere in between 7,4 and 4,8
2 ways
zero product property
easy way
zero product
factor perfect square
m^2-3^2=0
(m-3)(m+3)=0
set each to zero
m-3=0
x=3
m+3=0
m=-3
m=-3 or 3
easy way
add 9 to both sides
m^2=9
sqrt both sides remember to take postive and negative roots
m=+/-3
m=-3 or 3
B is answer
The correct option is -33/65.
The solution is given below:
Since the equation is:
<span>P(x)=-5x^2+40x-300
Solving the equation by using the calculator, the values for x are:
x = 4.72
