The expression "5 times x squared" can be represented as 5x^2, where x is a variable representing an unknown value. This expression indicates that the variable x is squared (multiplied by itself) and then multiplied by 5. The result of evaluating this expression will depend on the specific value assigned to x.
5x X x^(2) = 5x^(3) ; Said as 'five 'x' cubed'.
5x cubed
125x squared
It is 5x2 - 20
(5x)2 = 25x2.
When you subtract 7x^2 from 5x^2, you get -2x^2.
(5x - 2y)(5x + 2y)
5x squared
-1

(3x2)2 (5x)4 = 9x4625x4 = 5625x8
5x2 - 20 = 0x2 - 4 = 0x2 = 4x = +2 and -2
