​

Answer 1

Heya mate!!

$6 {a}^{2} - a - 15$

$6 {a}^{2} - (10 - 9)a - 15 \\ 6 {a}^{2} - 10a + 9a - 15 \\ 2a(3a - 5) + 3(3a - 5) \\ (2a + 3)(3a - 5)$

Hope it helps you dear✌️✌️

Answer 2

Answer:

-3/2 or 5/3

Step-by-step explanation:

(6a)^2 - a -15

= (6a)^2 -10a +9a - 15

= 2a(3a - 5) + 3(3a - 5)

= (2a + 3) (3a - 5)

The quadratic equation is 0

So,

Either

2a + 3 = 0

= 2a = - 3

= a = -3/2

or 3a - 5 = 0

=3a = 5

= a = 5/3
