Factor each trinomal

-6x^2-9

-2x^2+22x-48

-3 (2 x^2 + 3)

-2(x - 3) (x - 8)

Step-by-step explanation:

Factor the following:

-6 x^2 - 9

Factor -3 out of -6 x^2 - 9:

 -3 (2 x^2 + 3)

Factor the following:

-2 x^2 + 22 x - 48

Factor -2 out of -2 x^2 + 22 x - 48:

-2 (x^2 - 11 x + 24)

The factors of 24 that sum to -11 are -3 and -8. So, x^2 - 11 x + 24 = (x - 3) (x - 8):

-2(x - 3) (x - 8)

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
