Question

find the zeros of verify the relation between zeros and coefficient of xsqure+11x+30​

Answer 1

Answer:

We can find the zeros by Factorization method....

x² + 11x +30

x² + (6+5) x +30

x² + 6x +5x +30

x ( x+6 ) + 5 ( x+6 )

( x+6) ( x+5)

x = -6 , x = -5

To verify the relation between the zeroes and coefficient......

we will put the values of x in the place of x....

x² + 11x + 30 = 0

(-6)² + 11 × -6 +30 = 0

36 + (-66) + 30 = 0

36 -66 + 30 = 0

-30 + 30 = 0

hence it is a zero of the equation

x² + 11x +30

(-5)² +11×-5 +30 =0

25 + (-55) + 30 = 0

-25 + 55 + 30 = 0

-30 + 30 = 0

hence it is a zero of the equation

So we have two verified zeroes (-5) & (-6).....
