Answer 1

Answer:

i)a=3, b=6, c=9

Quadratic equation

=ax²+bx+c

=3x²+6x+9

=x²+2x+3

α+β=2, αβ=3

ii)a=1, b=(-3), c=2

Quadratic equation

=ax²+bx+c

=1x²+(-3)x+2

=x²-3x+2

α+β=(-3), αβ=2

iii)a=2, b=(-8), c=5

Quadratic equation

=ax²+bx+c

=2x²+(-8)x+5

=2x²-8x+5

α+β=(-8), αβ=5

iv)a=4, b=6, c=2

Quadratic equation

=ax²+bx+c

=4x²+6x+2

=2x²+3x+1

α+β=3, αβ=1
