Hi boys can you me will mark !
factor completely.

5x^2 - 45

a.

5(x + 3)(x - 3)

b.

5(x2 - 45)

c.

5(x - 9)(x + 9)

d.

(5x + 9)(x - 5)

A

Step-by-step explanation:

Given

5x² - 45 ← factor out 5 from each term

= 5(x² - 9)

x² - 9 is a difference of squares and factors in general as

a² - b² = (a + b)(a - b), thus

x² - 9

= x² - 3² = (x + 3)(x - 3)

and

5x² - 45

= 5(x + 3)(x - 3) → A
