Answer:

1, 2, 3, 6

Step-by-step explanation:

This questions is asking the GCF of 42 and 90. To find them, we have to find all their factors.

<u>42</u>                      <u>90</u>

1, 42                  1, 90

2, 21                  2, 45

3, 14                  3, 30

6, 7                   5, 18

                         6, 15

                         9, 10

Now we find the numbers that match up.

They both share 1, 2, 3, and 6 thus this is our answer

Which shows the correct substitution of the values a, b, and c from the equation –2 = –x + x2 – 4 into the quadratic formula? Qu
Likurg_2 [28]

Answer:

a  =  1

b =  -1

c =  -2

Step-by-step explanation:

We reorder the equation in such way that let us see the usual

ax² + bx + c = 0

Then the original quation is:

-2 = - x + x² - 4               ⇒  0 = 2 - x + x² - 4        ⇒ x² - x  - 2  = 0

Now we are able by simply inspection to identify a, b . c comparing our equation with the general equation so :

a  =  1

b =  -1

c =  -2
