check the picture below.
so, notice there, the rhombus is really just two triangles, each triangle has a base of 4 units and a height of also 4 units, so simply let's get the area of a triangle and multiply that times 2.
![\bf \stackrel{\textit{area of 2 triangles}}{2\left[\cfrac{1}{2}(4)(4) \right]}\implies 16](https://tex.z-dn.net/?f=%5Cbf%20%5Cstackrel%7B%5Ctextit%7Barea%20of%202%20triangles%7D%7D%7B2%5Cleft%5B%5Ccfrac%7B1%7D%7B2%7D%284%29%284%29%20%5Cright%5D%7D%5Cimplies%2016)

Simplify ——————
a2 - 9
Equation at the end of step
3
:
a 3 1
(————————————————— + —————) - ————— = 0
(a + 3) • (a - 3) a - 3 a + 3
Equation at the end of step
4
:
(4a + 9) 1
————————————————— - ————— = 0
(a + 3) • (a - 3) a + 3
Pull out like factors :
3a + 12 = 3 • (a + 4)
Equation at the end of step
6
:
3 • (a + 4)
————————————————— = 0
(a + 3) • (a - 3)
3•(a+4)
——————————— • (a+3)•(a-3) = 0 • (a+3)•(a-3)
(a+3)•(a-3)
a+4 = 0
Subtract 4 from both sides of the equation :
a = -4
