Question

Find the zero of the quadratic polymial f(x)=x2+7x+12 and verify the relation between its o and coefficient

Answer 1

Answer:

Zeroes of quadratic equation are -3 and -4

Step-by-step explanation:

f(x)=x^2+7x+12 compare with ax^2+bx+c=0

here a=1,b=7,c=12

x^2+7x+12=0

x^2+3x+4x+12=0

(x+3)(x+4)=0

x=-3 or x=-4

Zeroes of quadratic equation are -3 and -4

sum of zeroes=-3-4=-7 =-b/a

product of zeroes=(-3)(-4)=12=c/a
