Which is the factorization of 8x2 + 13x - 6? G C
A
(8x - 3)(x + 2)
(x-6)(8x + 1)
(2x - 2)(4x + 3)
(4x - 1)(2x + 6)

(8x - 3)(x + 2)

Step-by-step explanation:

A factorization must have a result equals to the original expression.

In this question:

For each option, we test to see if the result is equal, applying the distributive property and then combining like terms.

(8x - 3)(x + 2)

8x² + 16x - 3x - 6 = 8x² + 13 - 6

Equal, so this is the factorization.

(x-6)(8x + 1)

8x² + x - 48x - 6 = 8x² - 47x - 6

Different

(2x - 2)(4x + 3)

8x² + 6x - 8x - 6 = 8x² - 2x - 6

Different

(4x - 1)(2x + 6)

8x² + 24x - 2x - 6 = 8x² + 22x - 6

Different

(x+3)(x+7)

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
