Question

find the zeros of the quadratic polynomial x²-7 x + 12 and verify the relationship between the zeros and the coefficient

Answer 1

hope this helps u ...frnd

Answer 2

x²-7x+12 = x² -3x -4x +12
               = x(x-3) -4(x-3)
               = (x-4)(x-3)
x-4=0
x=4

x-3=0
x=3

Therefore the zeroes are 4 and 3.

VERIFICATION

Sum of zeroes
α+β= -b/a
4+3= -(-7/1)
7=7

Product of zeroes
αβ= c/a
4×3= 12/1
12=12
