Sir. One doubt. Chapter - surface area and volume Q. A sector of a circle of radius 12cm has the angle 120°. It is rolled up so that two bounding radii are joined together to form a cone. Find the volume of the cone ?
Bro see Imagine that sector and take the radii of that sector and join them with each other a cone will appear the find the length of arc and equate with circumference of base circle of cone than you can find everything

11:13 ans
x=-2
p(x)=2x+4
p(-2)=2(-2)+4
=-4+4
=0
x=-2 is zero of polynomial p(x)
x+2 is a factor of p(x)

Pray for me Friends Tomorrow is my half yearly exam😅
18:10 answer is 1,124,864
We know,
x = -2
Then,
P(x) = P(-2)
2(-2) + 4
-4 + 4 = 0
If x = -2 is zero of P(x)
Then, x+2 is factor of P(x)
FACTOR THEOREM

X = -5/2
11:05 -Yes
Thank you Sir for this lecture Best of luck for exam everyone
2x + 4
x+2 as a factor
Means -2 ons the place of x
=> 2(-2) + 4
=> -4+4
=> 0
Hence, x+2 is a factor of p(x)
wrong
@@swar2315kaise be?
@@swar2315 YOU ARE WRONG
If there is +2 then u need to keep +2 in brackets the answer will be 8 then x+2 is is not factor of p(x)
wrong
2x+4 where x=-2 so, 2(-2)+4= -4+4=0 hence x=-2 is the 0 of polynomial and x+2 is the factor of the polynomial
Thank you so much sir 17 October se exam hai 😊
