Question

factories the following expression
1. x²+11x+30
2. x²-11x-42
3. z²-12z+27
4. p²-5p-6
5. p²+p-56

​

Answer 1

Step-by-step explanation:

=x²+11x+30

= x²+5x+6x+30

= x(x+5)+6(x+5)

= (x+5)(x+6)

=x²-11x-42

= x²+3x-14x-42

= (x+3)(x-14)

=z²-12z+27

= z²-3z-9z+27

= (z-3)(z-9)

=p²-5p-6

= p²+p-6p-6

= (p+1)(p-6)

=p²+p-56

= p²+8p-7p-56

= (p+8)(p-7)
