WitrynaFinding roots is looking at the factored form of the polynomial, where it is also factored into its complex/ imaginary parts, and finding how to make each binomial be 0. In a degree two polynomial you will ALWAYS be able to break it into two binomials. So it has two roots, both of which are 0, which means it has one ZERO which is 0. Witryna1 maj 2024 · A complex number is the sum of a real number and an imaginary number. A complex number is expressed in standard form when written a + bi where a is the real part and bi is the imaginary part. For example, 5 + 2i is a complex number. So, too, is 3 + 4√3i. Figure 3.1.1.

WitrynaImaginary or complex roots will occur when the value under the radical portion of the quadratic formula is negative. Notice that the value under the radical portion is represented by "b 2 - 4ac". So, if b 2 - 4ac is a negative value, the quadratic equation is going to have complex conjugate roots (containing "i "s). Witryna19 paź 2024 · The axis of symmetry is the real part of the complex roots; the imaginary part can be found by subtracting the square of the axis (here, $4$) from the intercept ($13-4=9$) and then taking the square root ($3$). This assumes the roots come in conjugate pairs (so the coefficients of your quadratic are real numbers). $\endgroup$ –
