Irrational and unequal roots
WebCLAIM: the square root of a non prime number is rational. Take 8 for example. 8 is not prime, correct. But, √8 = √4·√2 = 2·√2. Now the 2 in √2 is prime and therefore the square root of it IS irrational, and an irrational number times a rational number is ALWAYS irrational. WebThe roots can be easily determined from the equation 1 by putting D=0. The roots are: x = − b 2 a o r − b 2 a D < 0: When D is negative, the equation will have no real roots. This means the graph of the equation will not intersect …

Calculate the discriminant value of a cubic equation to discover the nature of its roots. The cubic equation has real roots if the discriminant is zero and all the coefficients of the cubic equations are real.
WebYou can lump the final two terms together, as neither of them involves x. So here, A = 1, B = -2a and C = 2a^2 + 1 (I've used capital letters for A, B and C since you've already used the variable 'a' in your quadratic). The discriminant is B^2 - 4AC, which is (-2a)^2 - 4 (2a^2+1) = 4a^2 - 8a^2 - 4 = -4 (a^2 + 1). What does this mean? WebIf = b² -4 a c = 0, then roots are rational and equal. If = b² -4 a c > 0, and is a perfect square of a rational number, then roots are rational and unequal. If = b² -4 a c > 0 but is not a square of rational number, then roots are irrational and unequal. They form a pair of irrational conjugates p + q, p - q where p, q Q, q> 0.
