The graphs of both equation are attached
The graphs are identical to each other and the zero are
(-2, 0) and (-1/2, 0)
The zeros are equal
How to show that the graphs are identical
The equation is rearranged to show the are identical and will result to similar graph
Expand the equation
(2x+1) (x+2)
= 2x² + 4x + x + 2
= 2x² + 5x + 2
