AstralOfficialAcc · Answer

Equation: 2b² - 19b + 709 = 0Use quadratic formula:b = [19 ± √((-19)² - 4(2)(709))] / (2·2)b = [19 ± √(361 - 5672)] / 4b = [19 ± √(-5311)] / 4Since the discriminant is negative, the roots are complex:b = (19 + √(-5311)) / 4b = (19 - √(-5311)) / 4Or in imaginary form:b = (19/4) ± (√5311 / 4)i
