Answer 2

I WILL SEND YOU THE ANSWER THROUGH A PIC.

IT CAN BE DONE IN 2 WAYS:

1.USING QUADRATIC FORMULA

2.SPLITTING THE MIDDLE TERM

REMEMBER QUADRATIC FORMULA IS ONLY FOR QUADRATIC POLYNOMIAL.

IF YOU FEEL SPLITTING MIDDLE TERM IS DIFFICULT YOU CAN USE QUADRATIC FORMULA.

BUT FOR FEW QUADRATIC POLYNOMIALS SPLITTING THE MIDDLE TERM WON'T BE APPLICABLE SO YOU SHOULD USE QUADRATIC FORMULA IN THAT CASE.
