- Apply Perfect Square Formula


X < y is the answer to this question
3x^2-24x-21 would be your answer
I think the answer you are looking for is 28.
7/8 multiplied by 32 gives you 28.
We know,
sin(x) and cos(x) have minimum value equal to -1 and maximum value is 1.
Maximum value of sin(x) is 1
So we replace sin by 1 in our given equation

When we replace sin by 1 we will get

y= -2+5 = 3
So maximum value is 3
