Four times a number x equals 4x.

x = number Four times the number (4x) is the same as the number increased by 78 (x + 78). Since they are both equal, then 4x = x + 78 4x - x = 78 3x = 78 x = 26

She isn't. 4x squared is 4 times (x squared). That is, 4 times (3 squared) = 4 times 9. If you want it to be the square of 4x (which would be the square of 4 times 3, ie, 12), you have to write it as (4x)squared.

(x + 4) (x - 4) = x2 - 16To work this out you need to multiply each term in the first bracket by each term in the second bracket.So you would do x times x which gives you x2.Then x times -4 which is -4x.Then 4 times x which 4x. (Note: this 4x will cancel out the -4x)And finally 4 times -4 which is -16.So you end up with x2 - 4x + 4x - 16 which equals x2 - 16.

A lack of spacing between symbols indicates multiplication. In this case, "4x" is another way of saying "4 times x", or "x + x + x + x". 'x' is an unknown variable. For example, if you were to say: 4x = 8 That's a way of saying "four times a certain value is equal to eight". The solution in this case is that x equals two, as four times two is equal to eight. You can see this by dividing both sides of the equation by four: 4x = 8 4x / 4 = 8 / 4 x = 2
