Answer:

An event can cause changes to occur in one or more of the spheres, and/or an event can be the effect of changes in one or more of Earth's four spheres. This two-way cause and effect relationship between an event and a sphere is called an interaction. Interactions also occur among the spheres.

Answer:

The roots of a quadratic equation are the values of the variable that satisfy the equation. They are also known as the "solutions" or "zeros" of the quadratic equation. For example, the roots of the quadratic equation x2 - 7x + 10 = 0 are x = 2 and x = 5 because they satisfy the equation. i.e., when each of them is substituted in the given equation we get 0.

Step-by-step explanation:

when x = 2, 22 - 7(2) + 10 = 4 - 14 + 10 = 0.

when x = 5, 52 - 7(5) + 10 = 25 - 35 + 10 = 0.

But how to find the roots of a general quadratic equation ax2 + bx + c = 0? Let us try to solve it for x by completing the square.

ax2 + bx = - c

Dividing both sides by 'a',

x2 + (b/a) x = - c/a

Here, the coefficient of x is b/a. Half of it is b/(2a). Its square is b2/4a2. Adding b2/4a2 on both sides,

x2 + (b/a) x + b2/4a2 = (b2/4a2) - (c/a)

[ x + (b/2a) ]2 = (b2 - 4ac) / 4a2 (using (a + b)^2 formula)

Taking square root on both sides,

x + (b/2a) = ±√ [(b2 - 4ac) / 4a2]

x + (b/2a) = ±√ (b2 - 4ac) / 2a

Subtracting b/2a from both sides,

x = - (b/2a) ±√ (b2 - 4ac) / 2a

x = (-b ± √ (b2 - 4ac) )/2a

This is known as the quadratic formula and it can be used to find any type of roots of a quadratic equation.
