When 10 is subtracted from the square of a number, the result is 3 times the number. Find the negative solution.

Step-by-step explanation:

Let the required number be x.

Therefore, according to the given condition:

Therefore, x = - 2 is the negative solution.

Good morning ☕️

Step-by-step explanation:

First ,we need to model the situation by expressing it as an equation

so, let x represent the uncknown negative number :

We get

x² - 10 = 3x

then

x² - 3x - 10 = 0

now using the quadratic formula:

Let Δ be the discriminant

Δ = b² - 4ac = (-3)² - 4(1)(-10) = 9 + 40 = 49 → √∆ = 7

Therefore

0 is its x and y coordinate

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
