Question

Find the zeroes of the quadratic polynomial x^2 + 7x + 10, and verify the relationship
between the zeroes and the coefficients.​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

X² + 7x + 10 = 0

x² + 2x + 5x + 10 = 0

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

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

x + 2 = 0 ; x = -2

x + 5 = 0 ; x = -5

Relationship between the zeroes and coefficient :-

Sum of zeroes = -2+(-5) = -2-5

= -7/1 = -x coefficient / x² coefficient

product of zeroes = -2(-5)

= 10/1 = constant / X² coefficient
