Factor x2 – 8x + 15. which pair of numbers has a product of ac and a sum of what is the factored form of the

-3, -5 ;;; (x-5)(x-3)

Step-by-step explanation:

The current equation we have is x² - 8x + 15

Now, we will have to filter the middle term is such a way that the there would be a common factor for the 2 groups out of the 4.

ok, so how do we divide the middle term?

Simple, we multiply the consonant in the equation with the numerical consonant of the first term...

The consonant we have : 15

numerical consonant: 1

The product would be 15 × 1 which is 15.

Now, we will have to break -8x in a way by which the two terms product would be 15.

The only possible way is -3 and -5

The equation now would be = x² - 3x - 5x + 15

Now, we will need to break these 4 terms to 2.

x ( x - 3 ) -5 ( x - 3 )

( x - 5 )( x - 3 )

Now, we got the factored form and the two numbers we have used are-3 and -5.

Hope I helped!

Answer

(-3,-5) and (x-3),(x-5)

Step-by-step explanation:

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
