1.





solutions:
if =>
if=>...double solution since we have factor twice
=>...double solution since we have factor twice




2.

.............recall the rule ; in your case and =>
now write it as a square of difference

...since factors are same, you will have two pairs of double roots
if =>=> or exact solution
=> or approximate



3.
