simplified it would equal: 24x to the third power - x to the second power - x to the sixth power - 34
x to the second power +11x+24 (x+_)(x+_) Is there a question here?

(x+3)2 = x2+6x+9
It is a polynomial expression in x. What about it?
x² + x² = 2x²

115 - 102 + (3 x 5) = 30
x^2 + 81

It equals 0. * * * * * Unless the question is (-x)2 + (+x)2. In that case, the answer is 2x2
