What is (8-3a2)(2a2+6)=

Step-by-step explanation:

open the bracket

8(2a2+6)-3a2(2a2+6)

(16a2+ 48)-(6a4+18a2)

16a2+48-6a4-18a2

-6a4-2a2+48

divide through by 6

-a4-(1/3)a2+8

where a=-1

b=-1/3

c=8

using the formula: -b+√(b2-4ac)

2a

-(-1/3)+√((-1/3)-4(-1)(8)

2(-1)

. 1/3+√(-1/3)+32

-2

1/3+√(-1+64)/3 +32

-2

1/3+√(63)/3 + 32

. no. ..

-2

1/3+√[21+32]

- 2

( 1/3+√54)/-2

1/3+3√2)/-2

(1+9√2)/-2

1+9√2)/-2. or. 1-9√2)/-2

0 is its x and y coordinate

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
