Question

8. Find the zeroes of the polynomial p(x) = 4x² - 7x +3 by factorising it and verify the
relationship between the zeroes and coefficient of p(x).​

Answer 1

Answer:

$4 {x}^{2} - 7x + 3 = 0 \\ 4 {x}^{2} - 4x - 3x + 3 = 0 \\ 4x(x - 1) - 3(x - 1) = 0 \\ (x - 1)(4x - 3) = 0 \\ x = 1 \: \: and \: \: \frac{3}{4}$

Relationship

$1 + \frac{3}{4} = \frac{ - ( -7 )}{4} = \frac{ - b}{a}$

And

$1 \times \frac{3}{4} = \frac{3}{4} = \frac{c}{a}$
