Solved Examples

Question 1: Find the value of x in the quadratic equation 5x2 - 4x + 6 = 0 ?
Solution:
 
x2 - 5x + 6 = 0
The formula for solving the polynomial equation is,

x = $\frac{-b \pm \sqrt{b^{2}-4ac}}{2a}$

x = $\frac{5 \pm \sqrt{(5)^{2}-4(1)(6)}}{2(1)}$

x = $\frac{5 \pm \sqrt{25-24}}{2}$

x = $\frac{5 \pm \sqrt{1}}{2}$

x = $\frac{5 \pm \sqrt{1}}{2}$

x = $\frac{6}{2}$ or $\frac{4}{2}$

x = 3 or 2

 

Question 2:
72 $\times$ 75 = ?

Solution:
 
72 $\times$ 75
= 72+5
= 77
= 823543
