Question

what number makes this equation true?
v^2+10v+16=(v+8)(v+?)

Answer 1

what number added to 8 gives you 10 and multiplied by 8 gives you 16 ?

Answer 2

@mena_loves_you .
divide the Equation with (v+8) as the first step..

Answer 3

2 right? Sorry my computer is being a pain in the A$$

Answer 4

v^2 + 2v + 8v + 16 = (v+8) ( v+?)
v(v+2) + 8 (v + 2) = (v+8) ( v + ? )
(v+2) ( v + 8 ) = ( v+8) (v+?)

dividing (v+8) on both the sides we get
(v+2) = ( v + ? )
i.e.
v + 2 = v + ?

subtracting v from both sides we get
2 = ?

hence missing number = 2
