Question

Find the zero of the polynomial x² - 4x + 3​

Answer 1

Answer:

Zeros are 3 and 1.

GIVEN:

P(x) = x²-4x+3

TO FIND:

Zeros and to verify the relationship between zeros and coefficients.

SOLUTION:

=> x²-4x+3 = 0

=> x²-3x-x+3 = 0

=> (x²-3x)+(-x+3) = 0

=> x(x-3)-1(x-3) = 0

=> (x-3)(x-1) = 0

Either (x-3) = 0

=> x = 3

Either (x-1) = 0

=> x = 1

Formula:

=> Sum of zeroes (α+β) = -(Coefficient of x)/Coefficient of x²

=> Product of zeroes (αβ) = Constant term/ Coefficient of x²

Sum of zeros:

= 3+1

=> -(-4)/1 = -(Coefficient of x)/Coefficient of x²

Product of zeros:

= 3(1)

=> 3/1 = Constant term/ Coefficient of x²

the answer is 3 and 1
