Why is brayani wrong when she says when x equals 3 the value of 4x squared is 36?
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.
What is 4x squared times 4x squared?
