Assessment: JAMB UTME - Mathematics - 1988 Subject: General Mathematics

Question 1 Report

\sqrt{\frac{- b \pm b^{2} - 4 a c}{2 a}}

\frac{- b \pm \sqrt{p^{2} - 4 p b}}{2 a}

\frac{- q \pm \sqrt{q^{2} - 4 b p}}{2 p}

\frac{- q \pm \sqrt{p^{2} - 4 b p}}{2 p}

Answer Details

px2 + qx + b = 0
Using almighty formula

\frac{- b \pm \sqrt{b^{2} - 4 a c}}{2 a}

.........(i)
Where a = p, b = q and c = b
substitute for this value in equation (i)
=

\frac{- q \pm \sqrt{q^{2} - 4 b p}}{2 p}
