Quadratic equations can always be factored.
true
false

False.

Step-by-step explanation:

For example x^2 - x - 6 = 0  can be factored to (x - 3)(x + 2) = 0, but x^2 - x - 7 is prime (it cannot be factored).

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.
