Question

Factorise :
(x+6)•(x+2)=0
[This is a quadratic equation]​

Answer 1

x = -6

x = -2

Explanation:

Finding the zeros :

• (x + 6)(x + 2) = 0

By this, we understand that if either of the factors equals 0, then the expression's value will also be 0.

• x + 6 = 0 ⇒ x = -6
• x + 2 = 0 ⇒ x = -2

Solution :

1. x = -6
2. x = -2

Answer 2

• (x+6)(x+2)=0
• x(x+2)+6(x+2)=0
• x²+2x+6x+12=0
• x²+8x+12=0

The zeros are

• x=-6 and -2
