Question

If P=17x ³+15x²-7x+9 Q= 10x³-5x²+2x+1 R = 11x³ -6x²+5x+10 P+Q+R
plz answer​

Answer 1

write on a sequence and add all of this

Answer 2

Answer:

given, P = 17x ³+15x²-7x+9

Q = 10x³-5x²+2x+1

R = 11x³-6x²+5x+10

then ,

P+ Q+ R

(17x ³+15x²-7x+9) + (10x³-5x²+2x+1) + (11x³-6x²+5x+10 )

38x^3 + 4x^2 + 20
