Question

7x+2=10y What is the answer of this question ​

Answer 1

Answer:

Final result :

7x2 - 10y

Step-by-step explanation:

Changes made to your input should not affect the solution:

(1): "x2" was replaced by "x^2".

STEP1:

Equation at the end of step 1

7x2 - 10y

STEP2:

Trying to factor as a Difference of Squares: 2.1 Factoring: 7x2-10y

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 : 7 is not a square !!

Ruling : Binomial can not be factored as the

difference of two perfect squares

Final result :

7x2 - 10y
