Answer 1

Question

1. 2x² + 7x + 3
2. 3x² - x - 4

Solution

Solve this question by splitting middle term

1) 2x² + 7x + 3

= 2x² + 6x + x + 3

= 2x(x + 3) + 1(x+3)

= (x + 3)(2x+1)

2) 3x² - x - 4

= 3x² - 4x + 3x - 4

= x(3x - 4) +1(3x - 4)

= (3x - 4)(x + 1)

Answer 2

QUESTION :

• 2x² + 7x + 3
• 3x² - x - 4

SOLUTION :

• 2x² + 7x + 3

split middle term

= 2x² + 6x + x +3

= 2x(x + 3) + 1(x+3)

= (x+3)(2x+1)

• 3x² - x - 4

split middle term

= 3x² - 4x + 3x - 4

= x(3x - 4) +1(3x -4)

= (3x -4)(x+1)
