WebMar 13, 2024 · This exercise is a simple first degree equation. To solve it, you need to realize that in this type of equation, the letters are actually unknown which mean some number. In this case, the values of a and b are given, so just substitute in the equation and calculate. If a = 2 If b = 3 So the equation: 2a-b will be 2 (2) - 3 = 4-3 = 1 Weba 5 – b 5 = (a – b)(a 4 + a 3 b + a 2 b 2 + ab 3 + b 4) If n is a natural number a n – b n = (a – b)(a n-1 + a n-2 b+…+ b n-2 a + b n-1) ... {-b\pm \sqrt{b^{2}-4ac}}{2a}\end{array} \) Δ = b 2 − 4ac is called the discriminant; For real and distinct roots, Δ > 0; For real and coincident roots, Δ = 0; For non-real roots, Δ < 0;
