the mc001-1.jpg is blank

anonymous · Answer

I could've been able to solve it if it didn't had those extra stuffs at the end

mckenzieandjesus · Answer

I said it is blank thats the missing number

mckenzieandjesus · Answer

its y+ [blank]

Step by step solution :

Step  1  :
 Raise  c to the  1st power


Exponentiation : 


Equation at the end of step  1  :
  (((y2)+15y)+56)-((y+7)•((y+(m•c))-jpg))  = 0 


Step  2  :
 Raise  y to the  2nd power


Exponentiation : 


Equation at the end of step  2  :
  ((y2 +  15y) +  56) -  (y + 7) • (y + mc - jpg)  = 0 


Step  3  :
Simplify   y2+15y+56  -  (y+7)•(y+mc-jpg)


 3.1    Factor  -ymc+yjpg+8y-7mc+7jpg+56 

Try to factor this 6-term polynomial into (2-term) • (3-term) 

Begin by splitting the 6-term into two 3-term polynomials:

 -ymc+yjpg+8y  and  -7mc+7jpg+56 

Next simplify each 3-term polynomial by pulling out like terms:

 -y • (mc-jpg-8)  and  -7 • (mc-jpg-8) 

Note that the two simplified polynomials have  mc-jpg-8  in common

Now adding the two simplified polynomials we get 

 (-7-y)  •  (mc-jpg-8) 

Which is the desired factorization.



Equation at the end of step  3  :
  (-y - 7) • (mc - jpg - 8)  = 0 


Step  4  :
Solve   (-y-7)•(mc-jpg-8)  = 0 


Theory - Roots of a product :

 4.1    A product of several terms equals zero. 

 When a product of two or more terms equals zero, then at least one of the terms must be zero. 

 We shall now solve each term = 0 separately 

 In other words, we are going to solve as many equations as there are terms in the product 

 Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation : 

 4.2      Solve  :    -y-7 = 0 

 Add  7  to both sides of the equation : 
                      -y = 7 
Multiply both sides of the equation by (-1) :  y = -7 




Solving a Single Variable Equation : 

 4.3     Solve   mc-jpg-8  = 0 

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

We shall not handle this type of equations at this time.



One solution was found :
                   y = -7
