Step-by-step explanation:

just understand how it is done

Answer 2

S O L U T I O N :

We have quadratic polynomial p(x) = x² + 7x + 12 & zero of the polynomial p(x) = 0;

$\underline{\underline{\tt{Using\:\:by\:\:factorisation\:\:method\::}}}$

⇒ x² + 7x + 12 = 0

⇒ x² + 4x + 3x + 12 = 0

⇒ x(x + 4) +3(x + 4) = 0

⇒ (x + 4)(x + 3) = 0

⇒ x + 4 = 0  Or  x + 3 = 0

⇒ x = -4  Or  x = -3

Thus,

The α = -4 & β = -3 are two zeroes of the given polynomial .

Now,

As we know that for verification we can use two types method :

• Sum of zeroes
• Product of zeroes .
