Webwe found two roots. r= -2+i and r=-2-i why we choose u=1 instead of u=-1? • ( 1 vote) Flag Olivier Chassé St-Laurent 8 years ago It doesn't make a difference, since both constants are arbitrary. C1 cos -x = C1 cos x, and C2 sin -x = -C2 sin x. You can just use C2 instead of -C2, since it's arbitrary. ( 3 votes) Flag juzerbhagat25 6 years ago

WebRecalling the property of complex numbers for a positive number 𝑎 , √ − 𝑎 = 𝑖 √ 𝑎, we can rewrite this as 𝑥 = 2 ± 1 2 𝑖 √ 1 6 = 2 ± 1 2 × 4 𝑖 = 2 ± 2 𝑖. Hence, we have two solutions for the quadratic equation: 𝑥 = 2 + 2 𝑖, 𝑥 = 2 − 2 𝑖. In the previous example, we … Weby = x 2 + 2 x - 3 y = ( x + 1 ) 2 - 4 Show Vertex (-1, -4) Roots (1, 0), (-3, 0) Focus/Diretrix Locus Axis Y Intercept Show Grid Grid Axes Share this Graph Zoom In Center axis Center graph Parabola Animated Gifs More Quadratic Gifs
