The LCM (Least Common Multiple) of 2x7 and 4x9 is 36x63.
5x2=10 2x7=14 10+14=24
5+3=8x4=32-8=24+2=26x7=182 If order of operation is followed then the mutiplication has to be done first. Then you add/subract the rest of the numbers from left to right. 5 + 3 x 4 - 8 + 2 x 7 = X (3x4) (2x7) 5 + 12 - 8 + 14 = X X=23
2x7 - 15 = 14 - 15 = -1
The final answer is 112.
I'm going to assume the polynomial in question is 2x7+(3-2x3)+(5x8-4x) Expanding out the polynomial: 2x7+3-2x3+5x8-4x Order the terms by powers of x: 5x8+2x7-2x3-4x+3 Since 8 is the highest power of x, the degree of the polynomial is 8.
