Answer:
No solution
Step-by-step explanation:
4(8n-1)=19+32n
Distribute the 4 to 8n-1
32n-4=19+32n
Add 4 on both sides
32n=23+32n
Subtract 32n on both sides.
Both 32n's cancel out so you are left with 0=23 which is false.

Step-by-step explanation:
F ( x ) = x² + 2x - 24
{ factorising by middle term splitting method }
[ 24 = 2 × 2 × 2 × 3 ]
F ( x ) = x² + 6x - 4x - 24
F ( x ) = x ( x + 6 ) -4 ( x + 6 )
F ( x ) = ( x + 6 ) ( x - 4 )
It is the bigger and smallest va,lue of the function
