Math Problem Statement
одно число меньше другого
Solution
The task in the image is asking to find two numbers that meet the following conditions:
- One number is 57 less than the other.
- The product of these two numbers is -740.
Let the two numbers be and , where is the larger number. According to the problem, we have:
and
Substituting into the second equation:
Expanding this:
Rearranging the equation:
Now, we solve this quadratic equation. The general formula for solving a quadratic equation is:
For the equation , , , and . Let's calculate the discriminant and find the values of . math
Coefficients of the quadratic equation
a = 1 b = 57 c = 740
Calculate the discriminant
discriminant = b**2 - 4ac
Calculate the solutions using the quadratic formula
if discriminant >= 0: root1 = (-b + math.sqrt(discriminant)) / (2a) root2 = (-b - math.sqrt(discriminant)) / (2a) else: root1 = root2 = None
(root1, root2)The solutions to the quadratic equation are:
Now, we can find the corresponding values for using .
For :
For :
Thus, the two pairs of numbers are:
- and
- and
These are the two solutions that satisfy the conditions. The first pair is and , and the second pair is and .
