What are two numbers that add to 615 but multiply to -90000? I'm trying to factor the quadratic x^2+615x-90000
Cannot be factored. Use Quadratic Formula and get:
X1 = -737.1.
X2 = 122.1.
To find two numbers that add to 615 but multiply to -90000, we can create a quadratic equation using the given information. Let's assume the two numbers are a and b.
We know that the sum of the numbers is 615:
a + b = 615 (Equation 1)
And we also know that the product of the numbers is -90000:
a * b = -90000 (Equation 2)
To factor the quadratic equation x^2 + 615x - 90000, we need to find the values of a and b.
To find the values of a and b, we can rearrange Equation 1 to solve for a:
a = 615 - b
Now, substitute this value of a in Equation 2:
(615 - b) * b = -90000
This equation can be simplified to a quadratic equation:
b^2 - 615b - 90000 = 0
Now we can solve this quadratic equation to find the values of b. You can use the quadratic formula, factoring, or any other method to solve it.
After finding the values of b, substitute them back into Equation 1 to find their corresponding values of a.
Once you have the values of a and b, these will be the two numbers that add to 615 but multiply to -90000.
