Question

5g-20g(a+b)^ factorise it

Answer 1

Required Answer:-

Given to factorise:

• 5g - 20g(a + b)²

Solution:

Here, we will express the polynomial as a difference of two squares and then we will factorise it.

Here is the solution.

5g - 20g(a + b)²

= 5g [1 - 4(a + b)²]

= 5g[1² - (2(a + b))²]

= 5g[1² - (2a + 2b)²]

= 5g[(1 + 2a + 2b)(1 - 2a - 2b)]

= 5g(1 + 2a + 2b)(1 - 2a - 2b)

Hence, the factorised form is 5g(1 + 2a + 2b)(1 - 2a - 2b)

Answer:

• The factorised form of the given polynomial is 5g(1 + 2a + 2b)(1 - 2a - 2b)
