Answer 1

Answer:

Don't forget to mark me as brainliest.

Step-by-step explanation:

$bc( {a}^{2} + {d}^{2} ) + ad( {b}^{2} + {c}^{2} ) \\ = {a}^{2} bc + bc {d}^{2} + a {b}^{2} d + a {c}^{2} d \\ = {a}^{2} bc + a {b}^{2} d + bc {d}^{2} + a {c}^{2} d \\ = ab(ac + bd) +cd(bd + ac) \\ = (ab + cd)(ac + bd)$
