Question

Find the roots of quadratic polynomial
(1 Point)
x² - 7x​

Answer 1

Step-by-step explanation:

x2 - 7x = 0

x ( x - 7) = 0

x= 0 , x = 7

so the roots are 0,7

Answer 2

Answer:

= 10/1 = constant/x² coefficient

Step-by-step explanation:

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 coefficients :-

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

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

Product of zeroes = (-2)(-5)

= 10/1 = constant/x² coefficient

Hope it helps
