WebJun 25, 2024 · If (x+a) and (x+b) are two factors of a quadratic equation p (x), then the condition p (x) = (x+a) (x+b) = 0 must be satisfied. On simplifying the given polynomial, we get; p (x) = (x-1)²+2 (x+1) = x²+1-2x+2x+2 = x²+3 Now, Let us assume that p (x) has real roots. p (x)=0 => x²+3 = 0 => x² = -3 => x = √ (-3) WebTwo numbers r and s sum up to -2 exactly when the average of the two numbers is \frac{1}{2}*-2 = -1.
