Write: x^2 + 8x + 10 in the form (x + a)^2 + b

Step-by-step explanation:

Here, b=8 and c=10, so,

a=b/2

=8/2

=4

and

b=c-a²

=10-16

=-6

∴(x+a)²+b=(x+4)²-6

Pls mark me brainliest

hello there!

i believe the answer is

(cot2+1)/sec2=cot2

    csc2/sec2=cot2

  (1/sin2)/(1/cos2)=cot2

  (1/sin2)(cos2/1)=cot2

  cos2/sin2=cot2

  (1/tan2)=cot2

  (cot2)=(cot2)

hope this !
