Simplify
4x + 3y2 – 724 + 524 + 11 - 4x + y2

4y2 - 189

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 4x+3y2)-724)+524)+11)-4x)+y2

Step  2  :

Trying to factor as a Difference of Squares :

2.1      Factoring:  4y2-189

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check :  4  is the square of  2

Check : 189 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares.

Final result :

 4y2 - 189

step-by-step explanation:

just plug in each number for x and see which ones work and don't

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint
