Question

pla solve it fastt...........

Answer 1

here is the solution dude....
${x}^{2} + 6x + 9 - 4 {y}^{2} \\ = {(x)}^{2} + 2 \times x \times 3 + {3}^{2} - {(2y)}^{2} \\ = (x + 3)^{2} - {(2y)}^{2} \\ = (x + 3 + 2y)(x + 3 - 2y)$
hope it helps...pls mark it brainliest...plss

Answer 2

Given Equation is x^2 + 6x + 9 - 4y^2.

(x + 3)^2 - 4y^2

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

We know that a^2 - b^2 = (a + b)(a - b).

Here a = x + 3, b = 2y

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

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


Hope this helps!
