(2-9x)^4 [2(1-4.5x)]^4 (2^4)(1-4.5x)^4 Using the binomial expansion formula 16[1+(4*(-4.5x))+(((4*(4-1))/(12)))(-4.5x)^2] 16[1-18x+121.5x^2] 16-288x+1944x^2

To find the gradient of a function, that has constant gradient you pick any two points. You label both the x and y co-ordinates of these two points.Then you subtract the y co-ordinates of these two points...

x=-4, x=3

Answer: Integral= x³/3+ x/2 - cos(x) -1/4 sin(2x) + C Using the general rule that integrating xⁿ results in x⁽ⁿ⁺¹⁾/(n+1), x² integrates to x³/3.sin(x...

To find the answer you must first differentiate the function and set this equal to zero. This forms the quadratic equation x^2+2x-3=0 which can then be solved either by factorisation or by using the q...
