First factorize all the terms
63c7
= 9 * 7 * c * c  7
Now look for common factor in the terms. We see that 7 is common in the first and the second term. Factor it out:
= 7 * (9 * c 1)
Now we see that we can rewrite the terms within the parenthesis as difference of two squares.
= 7 * [(3 * c)  1]
Futrther factorize the terms using difference of squares formula which states a  b = (a+b)*(ab)
continue...
Please share your work with us indicating exactly where you are stuck  so that we may know where to begin to help you.
