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

### Asked by slvindustries1 | 6th Nov, 2020, 07:39: PM

Expert Answer:

### x^{2} + 3x - 10 = 0
→ x^{2} + 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
^{ }

^{2}+ 3x - 10 = 0

^{2}+ 5x - 2x - 10 = 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
