Question

5) Fatorise : 2x^2 - 7x -15​

Answer 1

Answer:

(2x+3) (x-5)

Step-by-step explanation:

2x²-7x-15=2x²-10x+3x-15=2x(x-5)+3(x-5)=(2x+3)(x-5)

Answer 2

Solution:

Given To Factorise - 2x² - 7x - 15

To factorise this, we have to split the middle term. By splitting the middle term, we get,

= 2x² - 10x + 3x - 15

Now, take out 2x as common from first two terms,

= 2x(x - 5) + 3x - 15

Similarly, take 3 as common from last two terms,

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

Now take (x - 5) as common,

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

• Now, the given expression is factorised.

Answer:

• Factorised form – (2x + 3)(x - 5).
