Question

P(X)=x2+2x-3 i quadratic
polynomial then find the sum of
Zeros & Product of Zeroes​

Answer 1

Step-by-step explanation:

$x ^{2} + 2x - 3 \\ x ^{2} + 3x - x - 3 \\ x(x + 3) - 1(x + 3) \\( x + 3) \: \: ( x - 1) \\ x = - 3 \: \: \: \: \: \: \: x = 1 \\ \alpha = - 3 \: \: \: \: \beta = 1 \\ a \\ from \: the \: polynoial \\ a = 1 \: b = 2 \: c = - 3 \\ \alpha + \beta = - b \div a = 3 \\ \alpha \times \beta = c \div a = - 3$
