Question

factorize the following expression​

Answer 1

Step-by-step explanation:

A² -4a + 3 +2b - b²

A² -4a + 3 +2b - b² = a² - 4a + 4 - 1 + 2b - b²

A² -4a + 3 +2b - b² = a² - 4a + 4 - 1 + 2b - b² = (a - 2)² - { b² -2b +1 }

A² -4a + 3 +2b - b² = a² - 4a + 4 - 1 + 2b - b² = (a - 2)² - { b² -2b +1 }= (a -2)² - (b -1)²

A² -4a + 3 +2b - b² = a² - 4a + 4 - 1 + 2b - b² = (a - 2)² - { b² -2b +1 }= (a -2)² - (b -1)² [ use, formula, x² - y² = (x - y)(x + y) ]

A² -4a + 3 +2b - b² = a² - 4a + 4 - 1 + 2b - b² = (a - 2)² - { b² -2b +1 }= (a -2)² - (b -1)² [ use, formula, x² - y² = (x - y)(x + y) ]=(a -2 - b +1 )(a -2 + b -1)

A² -4a + 3 +2b - b² = a² - 4a + 4 - 1 + 2b - b² = (a - 2)² - { b² -2b +1 }= (a -2)² - (b -1)² [ use, formula, x² - y² = (x - y)(x + y) ]=(a -2 - b +1 )(a -2 + b -1)=(a - b -1)(a + b -3)
