Using the general quadratic formula [10] gives: x=−2±16−162=2Therefore, we have two roots with x = 2. We may now rewrite the equation in the form (x − 2)(x − 2). This, when multiplied out, gives x2 − 4x + 4. (c) Using the general quadratic formula [10] giv...
Let us convert the standard form of a quadratic equation ax2 + bx + c = 0 into the vertex form a (x - p)(x - q) = 0. Here, (p, 0) and (q, 0) are the x-intercepts of the quadratic function f(x) = ax2 + bx + c) and hence p and q are the roots of the ...
If you can memorise a certain formula you can write down the roots of a quadratic equation with hardly any effort of calculation. Although it looks hard, this formula is one of the two most memorable ones in mathematics. Since it has to apply to any quadratic equation we must represent ...
IB Mathematics tutors can also explain the concept of conjugate roots with the help of the quadratic formula. In a quadratic equation, ax²+bx+c=0 if a, b and c are all rational numbers and one root of the quadratic equation isa+√bthen the second root will automatically becomea-√b...
