g(x) = e^(x-1) + x - 6 Show that the equation g(x) = 0 can be written as x = ln(6 - x) + 1, where x<6

0 = e x-1 + x - 6 e x-1 = 6-x x-1 = ln (6-x) -&gt; here we have taken the natural log of both sides, but it only shows on one side as the natural log of e is 1.x = ln (6-x) + 1Question taken from Edexcel 201...

Find the coefficient of x^4 in the expansion of: x(2x^2 - 3x + 1)(3x^2 + x - 4)

Only the terms which will form the x 4 term need to be considered:x * 2x 2 * x + x * -3x * 3x 2 = -7x 4 Therefore the answer is -7.
