-12 +/- sq root 104
(x2 plus 40) (x minus 1)
x^2+2x+40 = x^2-x+190Subtract x^2 from both sides2x+40 = -x+190Add x to both sides3x + 40 = 190Subtract 40 from each side3x = 150Divide both sides by 3x = 50
x2+14x+40 = (x+4)(x+10) when factored
4x + 20
Factor out -2: -2(x squared +11x-20). This is fully factored.
x2 + 48x + 320
Times 16 times 25 = 400 now what times to 400 and adds to 40 list the things that add to 40= 5+35 = 40 but 5 times 35 is 175 so it doesn't work 10+30 = 40 but 10 times 30 is 300 so it doesn't work but going in the right direction 20 +20 = 40 and 20 times 20 is 400 so we found our factors (16X+20) (16x+20) but wait they can be divided by 4? ----------- ---------- 4 4 (Note if they can be divide by different numbers you can) (4X+5)(4x+5) is the factor of it!
x - 2
-12 +/- sq root 104
1 squared radical 40 is equal to 1 squared radical (4 x 10), and this become 2 squared radical 10. By adding 2 squared radical10 with 3 squared radical 10 we get 5 squared radical 10.

x^2+2x+40 = x^2-x+190Subtract x^2 from both sides2x+40 = -x+190Add x to both sides3x + 40 = 190Subtract 40 from each side3x = 150Divide both sides by 3x = 50
2 squared plus 2 squared equals 16 because 2 squared is 4 times 4 equals 16. Math: 4x4=16 so your answer is 16 :)!
