Answer:

(x-6)(x-1)

Step-by-step explanation:

To find possible dimensions , we need to factor x^2 - 7x + 6

x^2 - 7x + 6

Here sum is -7  and product is 6

-1 times -6 = 6

-1 + (-6) = -7

Now we break -7x using factors -1  and -6

[tex]x^2 + 7x + 6[/tex]

[tex]x^2 -6x-1x + 6[/tex]

Now we do groping

[tex](x^2 -6x)+(-1x + 6)[/tex]

[tex]x(x -6)-1(x-6)[/tex]

factor out x-6

(x-6)(x-1)
