Question

QUADRATIC EQUATION
1. x2 + 3x +2 = 0​

Answer 1

Answer:

yes, it is a quadratic equation.

Answer 2

Answer:-

$\sf {x}^{2} + 3x + 2 = 0$

$\sf \implies {x}^{2} + x + 2x + 2 = 0$

$\sf \implies x(x+ 1)+ 2(x +1)= 0$

$\sf \implies (x+ 2)(x +1)= 0$

Therefore, either x+2=0 or x+1=0.

So,

x = -1 and x = -2.

These are the zeros.
