Question

find the zeroes of quadric polynomial and verify relationship between zeros and coefficient x^+7x+12​

Answer 1

Answer:

Step-by-step explanation:

x^2 +7x + 12

x^2 + 4x + 3x +12

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

=(x+3)(x+4)

Hence zeroes are x=-3, x=-4

Sum of zeroes = -3-4 = -7

=-b/a = -7/1

Product of zeroes = -4 × -3 = 12

=c/a = 12/1

Hence verified
