Use quad formula ^
a:-2
b:-16
c:-44

Answer 4

Can you do it @Sdowney?

Answer 5

\[ –2x^2 – 16x – 44 = 0 \rightarrow -2(x^2 + 8x + 22) = 0\]
i.e.\[ x^2 + 8x + 22 = 0 \rightarrow \]
Next use quadratif formula to find its solution

Answer 6

Answer 10

I'll try

Answer 11

Al right.

Answer 12

x=-b+-√b^2-4ac/2a
x=16+-√24

Answer 13

Now what?

Answer 14

Hm wait.

Answer 15

x=-4+-√24

Answer 16

Did you get how @dpasingh explained you find the common from this eq:
–2x2 – 16x – 44 = 0
-2 is the common so
x^2+8x+22=0
Put the quad formula
a:1
b:8
c:22
So,the answer is
-8 + sqrt -72/2
-

Answer 17
