Bruh it's 15. i mean if it is 15/15 then there is 15 things present yunno? idk but i hope this helped, have an amazing day :)

To solve this equation , we need to write it in quadratic form

To get the equation in quadratic form we replace x^2 with u

can be written as
, Replace u for x^2
So equation becomes

Now we factor the left hand side
-16 and -1 are the two factors whose product is +16 and sum is -17
(u-16) (u-1) = 0
u -16 = 0 so u=16
u-1 =0 so u=1
WE assume u = x^2, Now we replace u with x^2
Now take square root on both sides , x= +4 and x=-4
Now take square root on both sides , x= +1 and x=-1
So zeros of the function are -4, -1, 1, 4
(x^2 +5x+2.5^2) +4+5
(x+2.5)^2+9
