Question

Please help! :(
How would the expression (x^2+4)(y^2+9) be rewritten using Two Squares?

Answer 1

Use `a² + b² = (a + bi )(a - bi )` for `(x^2+4)` and for `(y^2+9)`

Answer 2

assuming that you have learned about the imaginary numbers and that you mean "Difference of squares" because that's what the question looks like.
