The factor of the algebraic expression 2a² + 2b² - 5ab is 2((a + b)² - 4.5ab)
How to factor the algebraic expression
From the question, we have the following parameters that can be used in our computation:
2a² + 2b² - 5ab
We can start by factoring out a 2:
2a² + 2b² - 5ab = 2(a² + b² - 2.5ab)
Also, we have
a² - b² = (a + b)(a - b)
This gives
(a + b)² = a² + 2ab + b²
This gives
a² + b² = (a + b)² - 2ab
So, we have
2a² + 2b² - 5ab = 2((a + b)² - 2ab - 2.5ab)
Evaluate
2a² + 2b² - 5ab = 2((a + b)² - 4.5ab)
Hence, the factor of the algebraic expression is 2((a + b)² - 4.5ab)
