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 )
Answer:
Surface Area of a Cube = 6
Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac
Surface Area of a Sphere = 4 pi r
Surface Area of a Cylinder = 2( pi
) + (2 pi r)* h
