A set of values that show an exact position. On graphs it is usually a pair of numbers: the first number shows the distance along, and the second number shows the distance up or down. Example: the point (12,5) is 12 units along, and 5 units up.

The one zero of the polynomial p(x)=x3 - 6x2+11x-6is 3 find the other two zeroes

Posted by Satyam Mishra 5 years, 5 months ago

CBSE > Class 10 > Mathematics

1 answers

Yogita Ingle 5 years, 5 months ago

p(x)=x³−6x²+11x−6

p(x)=(x−3)(x²−3x+2)
p(x)=(x−3)(x₂−2x−x+2)
p(x)=(x−3)(x−1)(x−2)

(x−1)(x−2)(x−3)=0

x=1,2,3

Thus, the other two zeroes of the polynomial are 1 and 2.

Posted by Beepanshu Kumar 5 years, 5 months ago

CBSE > Class 10 > Mathematics

2 answers

Arun Patel 5 years, 5 months ago

x²+(x+2)²=394 => 2x²+4x+4=394 => x²+2x-195 => x²-13x+15x-195 => x(x-१3)+15(x-13) => x=13 or -15 so if x =13 then x + 2 = 15 and if x = -15 then x+ 2= -13

Let two consecutive no be x and x+2 then A/q, x²+(x+2)²=394 => 2x²+4x+4=394 => x²+2x-195 => x²-13x+15x-195 => x(x-१3)+15(x-13) => x=13 or -15
