Assessment: WAEC SSCE - General Mathematics - 2004 (Objective) Subject: General Mathematics

Question 1 Report

Solve the equation 10-3x-x2 = 0
Answer Details
To solve the equation 10-3x-x2 = 0, we can first rearrange it to get x2+3x-10=0. We can then factorize this quadratic equation as (x+5)(x-2)=0. This means that either x+5=0 or x-2=0, which gives us the solutions x=-5 and x=2. Therefore, the correct answer is x=2 or -5, which is the first option.
