Question

25. Find the zeroes of the Quadratic polynomial x2 + x + 10 and verify the relationship
between the zeroes and the co-efficient.
06. A motor boat whose need is 15 km lhe is still water non 70 mm​

Answer 1

Answer:

when the quadratic polynomial is zero

x^2+X-10=0

x^2+(5-2)X-10=0

x^2+5x-2x-10=0

x(X+5)-2(X+5)=0

(X+5)(x-2)=0

X+5=0 and x-2=0

x=-5 and X=2

actually question is wrong...

correct question is

x^2 +X -10
