Simplify<br> 21x^6 y^5<br> 14x^2y^9
PIT_PIT [208]

Answer:

\frac{3x^{4} }{2y^{4} }

Step-by-step explanation:

Factor out 7 from top and bottom :

\frac{7(3x^6y^5)}{7(2x^2y^9)}

Divide top and bottom by 7 :

\frac{3x^6y^5}{2x^2y^9}

Simplify :  

\frac{x^6}{x^4}=x^{2}

Simplify :

\frac{y^5}{y^9} = y^{-4}  = \frac{1}{y^{4} }

Collect everything together :

\frac{3x^{4} }{2y^{4} }

Hope this helped and have a good day

For questions 1 - 2, use the distributive property to find the product of the binomials.
igor_vitrenko [27]

Answer:

1).  2x^2-3x+20

2). 4x^2-14x+6

Step-by-step explanation:

1. (x-4)(2x+5)

FOIL:

(x)(2x)+5(x)-8(x)+(4)(5)

2x^2+5x-8x+20

=2x^2-3x+20

2. (4x-2)(x-3)

FOIL:

(4x)(x)-(3)(4x)-2(x)-2(-3)

4x^2-12x-2x+6

=4x^2-14x+6
