Which of the following could be used as justification that 3x^2+10x-8 is not prime over the set of rational numbers

a. (3x+2)(x-4)
b. (3x+4)(x-2)
c. (3x-2)(x+4)
d. (3x-4)(x+2)

C

Step-by-step explanation:

Consider the trinomial

We can rewrite it as

Now group first two terms and last two terms:

The common factor in first two terms is and the common factor in last two terms is Use the distributive property for both groups of terms:

so

Now you can see that is a common factor, thus

Since the trinomial can be represented as a product of binomials, this trinomial is not prime.

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
