Perform the indicated operations:
1.(13x2-13x-15)+(-8x2-4x+14) the right side of the x is exponent the 2
2.(9b2+18b+9)+(8b2+18) the right side of b is exponent the 2
3.(-20x3+15x+4)+(3x3-14x2-2) the right side x is exponent the 3, 3, 2
4.(12x2+10x-14)-(10x2-12x-12) the right side of x is exponent the 2,2
5.(-15xy2+3xy-3)-(-2xy2-7) the right side of y is exponent the 2,2
