Why does minus 2 x minus 2 equal 4?
Using the distributive property of multiplication over addition, 2*[2 - 2] = 2*[2 + (-2)] = 2*2 + 2*(-2)LHS = 2*0 = 0RHS = 4 + 2*(-2)Therefore 2*(-2) = -4 and, by commutativity, -2*2 = -4Next-2*[2 - 2] = -2*[2 + (-2)] = -2*2 + -2*(-2)LHS = -2*0 = 0RHS = -4 + -2*(-2)Therefore -2 times -2 = +4
How do you find a constant k such that x minus 2 is a factor of x4 minus 5x3 plus kx2 plus 3x minus 10?
k = 7 x^4 - 5x^3 + 7x^2 + 3x - 10 = (x + 1)(x - 2)(x^2 - 4x + 5)
