Question no.1
6a²-a-15
​

Answer 1

Answer:

a = 5/3    or     a = -3/2

Step-by-step explanation:

6a² - a - 15 = 0

Using Factorization method,

6a² - 10a+ 9a - 15 = 0

2a(3a - 5) + 3(3a - 5) = 0

(3a - 5)(2a + 3) = 0

3a - 5 = 0                2a + 3 = 0

3a = 5                     2a = -3

$a=\frac{5}{3}$                        $a=\frac{-3}{2}$
