Answer:

Hi

Step-by-step explanation:

((16×(x))-((72×(x²))×((y²)))+3y

((16×(x))-((2³×3²×y²))+3y

(2x-(2³×3²x²y²))+3y

factoring 16-72yx²y²+81y⁴

Try to factor this multi-variable trinomial using trail and error

Found a factorization:(4x²-9y²)×(4x²-9y²)

16x-72x²y²+81y is. a perfect square

It factors into (4x²-9y²)×(4x²-9y²)

which is another way of writing (4x²-9y²)²

How to recognize a perfect square trinomial:

*It has three terms

*Two of its terms are perfect squares themselves

*The remaining term is twice the product of the square roots of the other two terms

Factoring:4-9y²

put the exponent aside,try to factor 4x²-9y²

Theory:A different 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 I therefore eliminated from the expression.

Check:4 is the square of 2

Check:9 is the square of 3

Check:x² is the square of x¹

Check:y² is the square of y¹

Factorization is:(2x+3y)×(2x-3y)

Rais the exponent which was put aside

Factorization becomes:(2x+3y)²×(2x-3y)²

Final result (2x+3y)²×(2x-3y)²
