Irrational and unequal roots
Did you know?
WebIrrational roots. The roots of quadratic polynomials can be nice, integer values. For example x2 +4x+3 x 2 + 4 x + 3 has x =−3 x = − 3 as a root. However, this is not always the case. … 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?
Web1. If b2- 4ac is a perfect square or zero,the roots are rational; otherwise they areirrational. 2. If b2- 4ac is negative (less than zero),the roots are imaginary. 3. If b2 - 4ac is zero, the … 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.
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.
