Answer 1

Solution

i) 2x²+5x+3

= 2x²+(2+3)x+3

= 2x²+2x+3x+3

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

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

2) 2x²-3x-2

= 2x²-(4-1)x-2

= 2x²-4x+1x-2

= 2x( x-2) +1(x-2)

= (x-2)(2x+1)

3) 3x²+10x +3

= 3x²+(9+1)x+3

= 3x²+9x +1x+3

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

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

4) 7x²-19x -6

= 7x²-(21-2)x-6

= 7x²-21x+2x-6

= 7x( x-3)+2(x-3)

= (x-3)(7x+2)

5) 7x-6x²+20

Compare with ax²+bx+c

6x²-7x-20

= 6x²-(15-8)x-20

= 6x²-15x+8x-20

= 3x(2x-5)+4(2x-20)

= (2x-5)(3x+4)

Hope IT HELPs : )

Answer 2

Answer:

(1) 2x² + 5x +3

= 2x² + 2x + 3x + 3

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

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

(2) 2x² - 3x - 2

= 2x² - 4x + x - 2

= 2x(x-2) + 1(x-2)

= (x-2)(2x+1)

(3) 3x² + 10x + 3

= 3x² + 9x + x + 3

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

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

(4) 7x² - 19x - 6

= 7x² - 21x + 2x - 6

= 7x(x-3) + 2(x-3)

= (x-3)(7x+2)

(5) 7x - 6x² + 20

= -6x² + 7x + 20

= -6x² - 8x + 15x + 20

= -2x(3x+4) + 5(3x+4)

= (3x+4)(-2x+5)
