Question

Help please it would mean a lot

Answer 1

(2) (x²-3y)(x²+3y)

Explanation:

x⁴-9y²

Factor/GCF:

x⁴ = (x²)(x²)

-9y² = (-3y)(3y)

Combine:

(x²-3y)(x²+3y)

Answer 2

2. (x^2 + 3y)(x^2 - 3y)

Explanation:

According to algebraic formula:

x^2 - y^2 = (x + y)(x - y)

We have x^4 - 9y^2 => (x^2)^2 - (3y)^2

=> (x^2 + 3y)(x^2 - 3y) or (x^2 - 3y)(x^2 + 3y)
