Question

-) Find the roots of quadratic equation x2 + 5x + 6 = 0
thana - 2​

Answer 1

Answer:

(2)²+5(2)+6=0

4+10+6=0

20

Answer 2

$x {}^{2} + 5x + 6 = 0 \\ x {}^{2} + 2x + 3x + 6 = 0 \\ x(x + 2) + 3(x + 2) = 0 \\ (x + 3)(x + 2) = 0 \\ x = - 3 \: or \: - 2$

Hence, the roots of the given p(x) are -3 & -2.
