Correct answer: product of two consecutive positive integers is 306
Explanation:
Let the two consecutive positive integers be \( x \) and \( x + 1 \).
Their product is: \[ x(x + 1) = x^2 + x \] Given: \[ x^2 + x = 306 \Rightarrow x^2 + x - 306 = 0 \] This matches the given equation: \( x^2 + x - 306 = 0 \)
Hence, the equation represents the product of two consecutive positive integers is 306.
If the roots of the quadratic equation \( ax^2 + bx + c = 0 \) are real and equal, then:
If the given figure shows the graph of polynomial \( y = ax^2 + bx + c \), then:
