Question

Factories:- 36x^2 - 12x + 1
4x^2 - 17x -21
10x^2 + 3x - 4
7x^ 2 - 25x - 12
5x^2 + 13 x - 6​

Answer 1

Answer:

1. ( 6x-1 ) (6x-1)

2.(x+1)(4x-21)

3.(2x-1)(5x+4)

4.(x-4) (7x+3)

5.(5x-2)(x+3)

Step-by-step explanation:

1. 36x^2-12x+1

36x^2-6x+6x +1

6x (6x-1) -1 (6x -1)

(6x-1) (6x-1)

2.4x^2-17x-21

4x^2-21x+4x-21

x(4x-21)+1(4x-21)

(x+1) (4x-21)

3.10x^2+3x-4

10x^2+8x-5x-4

2x(5x+4)-1(5x+4)

(2x-1)(5x+4)

4.7x^2-25x-12

7x^2+3x-28x-12

x(7x+3)-4(7x+3)

(x-4) (7x+3)

5.5x^2+13x-6

5x^2+15x-2x-6

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

(5x-2)(x+3)
