Question

x^2-y^2+2x+1 factorize the expression​

Answer 1

Answer:

$(x + y + 1)(x - y + 1)$

Step-by-step explanation:

$x {}^{2} - y {2} + 2x + 1 = x {}^{2} + 2x + 1 - y {}^{2} \\ = (x) {}^{2} + (1) {}^{2} + (2 \times x \times 1 )- y {}^{2} \\ = (x + 1) {}^{2} - y {}^{2} \\ = (x + 1 + y)(x + 1 - y)$
