What is x2-72x-735 factored?

Answer 1

I assume you mean;

X^2 - 72X - 735 = 0

The only way I would do this is by the quadratic formula

discriminant

(-72)^2 - 4(1)(-735) = 8124 and means two real roots

X = - b (+/-) sqrt(b^2-4ac)/2a

a = 1

b = - 72

c = - 735

X = - (-72) (+/-) sqrt[(-72)^2 - 4(1)(-735)]/2(1)

X = 72 (+/-) sqrt(8124)/2

X = [72 (+/-) 2sqrt(2031)]/2

Ugly, but true.
