Step-by-step explanation:

${x}^{2} + 2x - 15 \\ = (x - 3)(x + 5)$

then:

$4 {x}^{2} - 36 \\ = 4( {x}^{2} - 9) \\ = 4(x - 3)(x + 3)$

then pack them up!

4(x - 3)(x + 3)(x + 5)

tho there is a problem in your question.

lcm means the least common multiple.

answers in options are just multiples.

though considering that you shall choose:

$4(x + 5) {(x - 3)}^{2} (x + 3)$
