Question

give all the identities and all the formula of class 10th cbse ​

Answer 1

Euclid Devision Algorithm

a = bq + r where a > b , 0 ≤ r < b

Linear polynomial general form :- ax + b where a , b belongs to real numbers and a ≠ 0

quadratic polynomial :- ax2 + bx + c

cubic polynomial :- ax3 + bx2 + cx + d

Distance between 2 points => √(x2-x1)2 + (y2-y1)2

Trisection and section :- P = ( m1x2 + m2x1 / me + m2 , m1y2 + m2y1 / m1 + m2 )

Mid point = ( x1 + x2 / 2 , y1 + y2 /2 )

Centroid of a triangle :- G = ( x1 + x2 + x3 / 3 , y1 + y2 + y3 / 3 )

nth degree of arithmetic progression ===>
an = a + ( n - 1 ) d
where a = the 1st term b = common difference
d = a2 - a
