    Find an equation ax2+bx+c=0 such that the sum of the roots is 10 and the product of the roots is 4.

    Solution:
    To solve the problem we apply the formula for forming quadratic equation given below :
    x2-(sum of roots)x+product of roots=0
    From the question;
    Sum of roots=10
    Product of roots=4
    Substituting the value in the...

    In question number one we are ask to solve by factoring. Here are the solutions:

    (i)
     x2-12=0
    Factorizing gives:
    x(x-12/x)=0
    x-12/x=0
    x=12/x
    x2=12
    x=+√12 or -√12
    x=+2√3 or -2√3

    (ii)
    48-3x2=0
    Divide through by 3;
    16-x2=0
    Rearranging gives;
    x2-16=0
    (x+4)(x-4)...
