Which shows one way to determine the factors of 4x^3+x^2-8x-2

For this case we must factor the following expression:

We group the first two and the last two terms:

We factor the highest common denominator of each group:

We take the common factor

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.

hope it

i think asking google will you get the answer to that question
