Q
Q: The equation x^2 - 7x + 10 = 0 has roots that are:
Solution:
Factoring the equation gives (x - 2)(x - 5) = 0, so the roots are 2 and 5.
Steps: 7
Show Steps
Step 1: Start with the equation x^2 - 7x + 10 = 0.
Step 2: Look for two numbers that multiply to 10 (the constant term) and add up to -7 (the coefficient of x).
Step 3: The numbers -2 and -5 multiply to 10 and add to -7.
Step 4: Rewrite the equation using these numbers: (x - 2)(x - 5) = 0.
Step 5: Set each factor equal to zero: x - 2 = 0 and x - 5 = 0.
Step 6: Solve for x in each equation: x = 2 and x = 5.
Step 7: The roots of the equation are 2 and 5.
