〉〉 Without solving, comment upon the nature of the roots for following 3 Equations. Example 1: 6x² – 13x + 4 = 0 From ax² + bx + c=0; by comparing, we get a = 6, b = -13, c = 4; So coefficients are real. Discriminant ‘D’= b² – 4 a c ⇒ (-13)² […]
Equation: An equation is a mathematical sentence that uses the equal sign (=) to show that two expressions are equal. Example 1: 3+4=7 ; Example 2: 3a+4b=1
