Answer 1

Here is your answer

Hope it helps you !!

Answer 2

GIVEN :-

• 2x² - 5x - 12

TO FACTORISE :-

• 2x² - 5x - 12

SOLUTION :-

➵ 2x² - 5x - 12

By splitting the middle term,

➵ 2x² - 8x + 3x - 12

Taking common,

➵ 2x(x - 4) + 3(x - 4)

➵ (x - 4) (2x + 3)

Hence answer is (x - 4) (2x + 3)

ADDITIONAL INFORMATION :-

➵ ( a + b ) ( a + b ) = ( a + b )²

➵ ( a - b ) ( a - b ) = ( a - b )²

➵ ( a + b ) ( a - b ) = a² - b²

➵ ( x - y )² = x² - 2xy + y²

➵ ( x + y )² = x² + 2xy + y²

➵ ( x + a ) ( x + b ) = x² + x ( a + b ) + ab
