Question

verify
the relationship between Zeroes.and
roots of the quaratic polynomial

x² +11x + 18​

Answer 1

x^2 +9x+2x+18 = x(x+9)+2(x+9)

= (x+9)(x+2)

x= -9 / x = -2

$\alpha \beta = - 9 \times - 2 \\ = 18 \ \ \\ \alpha + \beta = - 9 - 2 \\ = - 11$

$c \div a = 18 \div 1 = 18 \ \\ - b \div a = - 11 \div 1 \\ = - 11$
