Question

3. Find the quadratic polynomial
whose zeroes are
1 by 4 and - 1​

Answer 1

Answer:

Step-by-step explanation:

We know that the quadratic polynomial with

zeros  α and  β is

$x^2-(\alpha +\beta)x +\alpha \beta \\\\Given \ \alpha =\frac14 \ and \ \beta =-1\\\\Thus \ the \ polynomial \ is\\\\\bf=x^2-(\frac14-1)x+(\frac14)(1)\\\\=4x^2+3x+1$
