Question

Solve- 3x2 + 5xy – 2

Answer 1

= -6 - 2+ 5xy
= -8 +5xy

Answer 2

3x²+5xy-2

it is in the form of ax²+bxy+c
compare with the above equation

a=3;b=5;c=-2
we know that

(-b±√(b²-4ac))/2a

substitute in above value in formula

(-5±√(5²-4(3)(-2))/2(3)
-5±√(25-24)/6

-5±1/6

-5+1/6;-5-1/6
-4/6;-6/6

-2/3;-1
