Question

please give me answer fastly 7th one ​

Answer 1

Answer:

in this question ..u have to verify relation between zeros and coefficients.. u can do so by using following formulas:-

sum of zeros = -b/a

product of zeros = c/a

the standard form of a quadratic polynomial is:-

ax^2+bx+c.

Answer 2

x square -4=0

x square =4

thus, x=-2,2

thus,

alpha +beta =-b/a=-0/-2or2=-2+2==0

alpha *beta=c/a=-4/-2or2=2or-2
