After you factor it, which parentheses are the answer?

If you were to use the FOIL rule and multiply out (x+3)(x+5), you would get x^2+8x+15

F = multiply first terms = x*x = x^2

O = multiply outer terms = x*5 = 5x

I = multiply inner terms = 3*x = 3x

L = multiply last terms 3*5 = 15

The four terms we get are x^2, 5x, 3x and 15

Add them up. Combine like terms

x^2+5x+3x+15 = x^2+8x+15

Therefore, (x+3)(x+5) = x^2+8x+15

With factoring, we think of this process in reverse

What two numbers multiply to 15 and add to 8? Those two numbers happen to be 5 and 3 which is where the (x+5)(x+3) comes from

lol, i have been using this product for a while and the second half of the year for a lon and the first time in a long time ago that the government has not yet received enough votes to be a good the first place in the world to be able to do it in my world life, i

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
