What are the factors of 3x^2+7x-20?

A factor is each of the numbers you are using

So the factors are:

Factor 1:    3x²

Factor 2:   7x

Factor 3:   -20

first multiply -20 by 3:

x^2+7x-60

then break down the factors of 60:

1,60  2,30  3,20  4,15  5,12  6,10

next figure out which factors multiply to =60 and subtract to equal 7

12-5=7   12*5=60

then you have:

(x+12)(x-5)

then see if 12 and 5 can be divided by 3 (12 can, 5 cant so you'd get the following)

(x+4)(3x-5)

then set both equal to 0 and solve

x+4=0  x=-4

3x-5=0  3x=5 x=5/3

the factors are {-4,5/3}

a and c

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
