Answer:
(x+2)(x+10)
Step-by-step explanation:
The given trinomial needs to be factorised. On the basis of degree of power of polynomial it can also be called a quadratic polynomial . General form is ax² + bx + c .
= x² + 12x + 20
- By splitting middle term .
= x² + 10x + 2x + 20
- Taking x and 2 as common.
= x ( x + 10 ) + 2( x + 10 )
- Talking (x + 10) as Common .
= ( x + 2)( x +10)
Hence the factorised form is (x+2)(x+10).
