y2-y-72 is an algebraic expression that can be factored as: (y+8)(y-9)
√3 - 9 is an expression, and so there is nothing to be solved. It can be evaluated - use a calculator!
It is: (g-5)(g-9)
8 - (9 - t)
(3 - i)(3 + i)
69
Negative 12 minus 3 plus 9 is equal to -6
9
(81 - m2) = (9 - m)(9 + m)
x2-81 = (x-9)(x+9)
3(n-9)
