Answer 1

Answer:

1. =(2x-1) (2x-3)
2. =(y-3) (y-7)
3. =(x+2) (x-8)
4. =(x-3) (x-4)
5. =(x+1) (x-5)
6. =(2x-1) (2x-5)

Step-by-step explanation:

1)4x^2-8x+3

=4x^2-6x-2x+3

=2x(2x-3)-1(2x-3)

=(2x-1) (2x-3)

2)y^2-10y+21

=y^2-7y-3y+21

=y(y-7)-3(y-7)

=(y-3) (y-7)

3)x^2-6x-16

=x^2-

=x^2-8x+2x-16

=x(x-8)+2(x-8)

=(x+2) (x-8)

4)x^2-7x+12

=x^2-4x-3x+12

=x(x-4)-3(x-4)

=(x-3) (x-4)

5)x^2-4x-5

=x^2-5x+x-5

=x(x-5)+1(x-5)

=(x+1) (x-5)

6)4x^2-12x+5

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

=2x(2x-5)-1(2x-5)

=(2x-1) (2x-5)
