Answer:Q.1 -4x^2-5x-8
Q.2 17
Q.3 13x+6y-17z
Q.4 17 x^3-11x^2-11
Q.5 5x^2 +6x+2
Step-by-step explanation:
Q.1 (3x^2+4x-2-2x^2+2x+1) -(6x^2-4x+5-x^2+15x+2)
X^2+6x-1-5x^2+11x+7x=-4x^2-5x-8.
Q.2 a=-2,b=-3 and c=-4
Then ,a^2+b^2-c
Putting the value of a,b ,c respectively
hence ,(-2)^2+(-3)^2-(-4)= 4+9+4=17.
Q.3 P= 3x+y-z, Q=15x+4y-8z, and R=5x-y+8z
Then, P+Q-R
Putting the value of P ,Q ,R respectively
Hence,3x+y-z+15x4y-8z-5x+y-8z=13x +6y-17z.
Q.4 (9x^3-7x^2-5)-(-2x^3+4x^2+1)+(6x^3-5)
=9x^3-7x^2-5+2x^3-4x^2-1+6x^3-11 = 17x^3-11x^2-11.
Q.5 Aman had initial money (/11x^2+10x-4)
He spent (6x^2+4x-6)
Money left (11x^2+10x-4-6x^2-4x+6)= 5x^2+6x+2.
