Answer:

x = 7, - 8

Step-by-step explanation:

x^2 + x - 56 = 0

x^2 + 8x - 7x - 56 = 0

x ( x + 8 ) - 7 ( x + 8 ) = 0

( x - 7 ) ( x + 8 ) = 0

x - 7 = 0

x = 7

x + 8 = 0

x = - 8

A and B are monomials where A = 125 and B = 27p12. What is the factored form of A – B?
steposvetlana [31]

Answer:

The correct option is A.

Step-by-step explanation:

Given:

A= 125

B = 27p^12

To find: A-B

A-B = 125 - 27p^12

A-B=(5)^3-(3p^4)^3

We know that, a^3 - b^3 = (a-b)(a^2+ab+b^2)

Using this formula and finding factored form of A-B:

=(5-3p^4)((5)^2+(5)(3p^4)+(3p^4)^2)

=(5-3p^4)(25+15p^4+9p^8)

So, factored form of A-B is: (5-3p^4)(25+15p^4+9p^8)

Option A is correct..

Simplify. ( w^2/-3u^4)^2. Write your answer without parentheses.
Rudiy27

Answer:

w^4 / (9u^8)

Step-by-step explanation:

( w^2/-3u^4)^2

We know that ( a/b) ^c = a^c  / b^c

( w^2) ^2/ (-3u^4)^2

We know that a^b^c = a^(b*c)  

w^(2*2)/ (-3u^4)^2

We know ( ab) ^c = a^c * b^c

w^4/ (( -3)^2 u^4^2)

w^4/(9 u^(4*2))

w^4 / (9u^8)
