who will solve this all they are toppers and genius ​

Answer 1

Q25) p(x) = 5x^2-3x+7

p(1) =5*(1*1) -3*1+7 (as x=1)

p(1) =5+7-3=9

Q26) p(x) =2x-3

2x-3=0

x=3/2 is the zero of the polynomial 2x-3

Q27) (x+y) ^3=x^3+y^3+3xy(x + y)

Q28) (√11-√7) (√11+√7)

( a -b) (a+b) =a^2-b^2

=(√11) ^2-(√7) ^2=11-7=4

Q29) (1,-1)=4 th quadrant (2,-2)=4 th quadrant (4,-5) =4 th quadrant and( 3,-4) = 3 rd quadrant

Q30) from y axis it is 7 units

Q31) Deegree of zero polynomial is not defined.
