Question

If x^2 + 3x + 5)(x^2 - 3x + 5) = m^2 - n^2, then find the value of m.​

Answer 1

Answer:

$({x}^{2} + 3x + 5)( {x}^{2} - 3x + 5) = {m}^{2} - {n}^{2}$

Step-by-step explanation:

$x {}^{2} + 3x + 5 \times x {}^{2} - 3x + 5 = m {}^{2} - n {}^{2}$

$x {}^{2} + 3x + 5x {}^{2} - 3x + 5 = m {}^{2} - n {}^{2}$

$x {}^{2} + 5x {}^{2} + 3x - 3x + 5 = m {}^{2} - n {}^{2}$

$6 {x}^{2} + 5 = m {}^{2} - n {}^{2}$
