Q1
If a quadratic equation has roots 2 and -3, what is the equation in standard form?
x^2 + x - 6 = 0
x^2 - x - 6 = 0
x^2 - x + 6 = 0
x^2 + 5x - 6 = 0
Show Solution
Copy
The equation can be formed as (x - 2)(x + 3) = 0, which expands to x^2 + x - 6 = 0.

Q
Q: If a quadratic equation has roots 2 and -3, what is the equation in standard form?
Solution:
The equation can be formed as (x - 2)(x + 3) = 0, which expands to x^2 + x - 6 = 0.
Steps: 6
Show Steps
Step 1: Identify the roots of the quadratic equation. The roots given are 2 and -3.
Step 2: Write the factors of the equation using the roots. For root 2, the factor is (x - 2). For root -3, the factor is (x + 3).
Step 3: Combine the factors into one equation: (x - 2)(x + 3) = 0.
Step 4: Expand the equation by multiplying the factors: (x - 2)(x + 3) = x^2 + 3x - 2x - 6.
Step 5: Simplify the equation: x^2 + 3x - 2x - 6 = x^2 + x - 6.
Step 6: Write the final equation in standard form: x^2 + x - 6 = 0.
