Answer:
Explanation:
(4x+5)(4x+5) - 3 = 5x(3)
Honestly, what I did first was I did the box method for this equation, meaning I made a square and put 4x+5 on opposite sides of the square and solved each little box in the square using multiplication.
Now this are all the answers I got,
4x*4x= 16
, 4x*5=20x, 4x*5= 20x, 5*5=25
Now, you rewrite the equation as
16
+40x+25-3 = 5x(3)
Distribute the same terms now.
16
+40x+22= 15x
