Question
Without solving, comment upon the nature of roots of the following equations
6x2 – 13x +4 =0
Solution
6x^2 - 13x + 4 =0
a = 6, b = -13 and c = 4
∴ Discriminant = `b^2 - 4ac`
`= (-13)^2 - 4(6)(4)`
= 169 - 96 = 73
Since 73 is not a perfect square, roots are irrational
Since D > 0, then equation has two irrational and unequal roots.
