Select the factors of x2 − 14x + 49. (x + 49)(x + 1) (x + 7)(x + 7) (x − 7)(x − 7) (x − 49)(x − 1)
To find the factors, you want to find two numbers that multiply to 49 and add to -14. Knowing that, it would (x-7)(x-7)
the answer is C yes
Looking at the expression x%5E2-14x%2B49, we can see that the first coefficient is 1, the second coefficient is -14, and the last term is 49. Now multiply the first coefficient 1 by the last term 49 to get %281%29%2849%29=49. Now the question is: what two whole numbers multiply to 49 (the previous product) and add to the second coefficient -14? To find these two numbers, we need to list all of the factors of 49 (the previous product). Factors of 49: 1,7,49 -1,-7,-49 Note: list the negative of each factor. This will allow us to find all possible combinations. These factors pair up and multiply to 49. 1*49 = 49 7*7 = 49 (-1)*(-49) = 49 (-7)*(-7) = 49
post all ur questions here if u wish

Factor Completely: 25x2 − 36 (25x − 6)(x + 6) (25x + 6)(x − 6) (5x + 6)(5x − 6) (5x − 6)(5x − 6)
but the answer is the third one
(5x)^2-6^2 =(5x+6)(5x-6)
The third one. You can double check by using foil 25x-30x+30x - 36 25x - 36

Using complete sentences, explain how to completely factor 3x2 − 3x − 60.
3x2−3x−60 Factor out the GCF of 3 from each term in the polynomial. Factor out the GCF of 3 from the expression 3x2. 3(x2)−3x−60 Factor out the GCF of 3 from the expression −3x. 3(x2)+3(−x)−60 Factor out the GCF of 3 from the expression −60. 3(x2)+3(−x)+3(−20) 3(x2)+3(−x)+3(−20) Factor out the GCF of 3 from 3x2−3x−60. 3(x2−x−20) In this problem 4⋅−5=−20 and 4−5=−1, so insert 4 as the right hand term of one factor and −5 as the right-hand term of the other factor. 3(x+4)(x−5)
or
wow you are fantastic at this you should be a teacher no joke lol
facter out 3 out of all of it.. all you do is you look at the problem, "3x^2-3x-60" looking at that there is a leading coefficient of 3 (3x^2) so you want to get the x^2 by itself, to do that you divide it all by 3 which gives you the 3(x^2-x-20)
u can also use that if u wish and ur welcome
what math class r u in?
i used the other one :) & algebra on virtual school
o
gl
lol thanks! :)
