Help please on this please

2x + 5

10x - 5

156

Step-by-step explanation:

similar here. after my answer to the other, very similar question you should be able to do this exactly along the same lines.

please refer to my other answer about the details of the reasons.

(g-h)(x) = 6x - 4x - (-5) = 2x + 5

(g+h)(x) = 6x + 4x - 5 = 10x - 5

(g×h)(x) = 6x×(4x - 5) = 24x² - 30x

(g×h)(-2) = 24×(-2)² - 30×-2 = 24×4 + 60 = 96 + 60 = 156

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

the discriminant is 64 + 4*1*12 = 112

this is prime.
