CBSE Class 10 Answered

Find the zeros of the quadratic polynomial n2+3x-10, and verify the relation between the zeros and its coefficients.

answered-by-expert Expert Answer
x2 + 3x - 10 = 0
→ x2 + 5x - 2x - 10 = 0
→ x(x + 5) - 2(x + 5)= 0
→ (x + 5)(x - 2)= 0
→ x = -5 or x = 2
 
Sum of the zeroes = -5 + 2 = -3 =-b/a  
Product of the zeroes = 5(-2) = -10= c/a
