3x² + 4x + 3 = 6x + 4

f(x) can be rearranged to be: f(x) = 1/6 x^-2This is then differentiated to be: f'(x) = -1/3 x^-3 as the expression is multiplied by the original power (-2) and then the power is red...

To answer the question the equation given must be rearranged into the straight line formula, y=mx+c, where m is the gradient of the slopeminus 4x from both sides, we now have 3y=12-4xthen divide through...

First, lets find 1%. TO do this, divide 654 by 100. This is because 654 is 100%, so 654/100 is 100/100% = 1%. Now that we have 1%, multiply this by 87 to find out what is 87%.

a) Take out the common factor, giving: 2(x²-36), idenitfy the difference of two squares and factoise accordingly, giving: 2(x-6)(x+6)
b) you have the facotirse version of the top of the fr...
