+3x-10 and verify the relation between its zeros and coefficient.Asked by pritymishtu | 20th Jun, 2014, 09:32: PM
Expert Answer:
We have p(x) = x2+3x - 10 = (x + 5)(x - 2)
For any zero, p(x) = 0
x2+3x - 10 = 0
(x + 5)(x - 2) = 0
(x + 5) = 0 OR (x - 2) = 0
x = - 5 OR x = 2
The zeroes of p(x) = x2+3x - 10 are as 
.
Now, sum of zeroes = 
= 
Product of zeroes = 
x2+3x - 10 = 0(x + 5)(x - 2) = 0(x + 5) = 0 OR (x - 2) = 0x = - 5 OR x = 2. = Answered by Mili Hariyani | 21st Jun, 2014, 09:49: AM
