Step-by-step explanation:

Let the number be 'x'

42% of x = 8.4

\dfrac{42}{100}*x=8.4\\\\x=8.4*\dfrac{100}{42}\\\\x=\dfrac{840}{42}\\\\x= 20

Trust me:  You must know how to do this basic factoring yourself.

x^2 -5x - 6 factors into (x-6)(x+1).  Note how I got that:  -6 is the product of 1 and -6, and -6 + 1 = -5.

You could also factor this by grouping:

x^2 -5x - 6 = x(x-6) + 1(x-6).  Note how the middle terms combine to produce -5x and how (x-6) is a factor common to both terms; this leaves (x+1).  So the factors are (x-6)(x+1).
