86 because you times -3 and 2 then you get -6. Then you times 10 and -8 and you get 80. Last thing is to add -6 and 80. You get 86.
For the person that answered with that, this is factoring! As in algebra!
-3x2+10x-8 -3*-8=24 6*4=24 6+4=10
-3x2+6x+4x-8
[3xx 2*3x] [2*2x 2*2*2]
-3x(x-2)+4(x-2)
(x-2)(-3x+4)
Answer: (x-2)(-3x+4) not 86...
simple mistake, whoever answered that simply thought it was arithmetic -3*2+10*-8.

-3x2 plus 10x - 8?
(-3x + 4)(x - 2)
Factor expression 3x2 plus 48x plus 192?
3x2 + 48 + 192 = 3x2 + 240 = 3 (x2+ 80)
How do you factor x squared plus 10x plus 16?
x^2 + 10x + 16 = (x + 8)(x + 2)
Factor x2 - 10x plus 16?
(x - 8)(x - 2)
How do you factor 3x squared plus 10x minus 8?
3x2 + 10x - 8The auxiliary equation is 3x2 + 10x - 24 [because 8*3 = 24] Two factors of -24 which sum to 10 are 12 and -2. So the factorisation of the auxillary is (3x + 12)*(3x - 2) = 3*(x + 4)*(3x - 2) Dividing by the 3 used to create the auxiliary gives the solution as (x + 4)*(3x - 2).
