Using the formula for differentiation: if y=ax^N then dy/dx= Na*x^N-1 apply this to each term in the equation given; first term: dy/dx= 9x²second term: dy/dx= 14xth...

A needs to be multiplied up by x+3 to make the fraction have the same in denominator as the other expressions. Then you need to equate the numerators. 3 - 5x = A(x+3) + B
You can gain two simultaneou...

A pain stimulus, for example, pressure from a pin, is sensed by a receptor, for example, pacinian corpuscle in the skin of the fingertip.This causes a change in shape of the receptor, so sodium ions diffu...

We know the discriminant (b^2 - 4ac) must be equal to zero for an equation to have equal roots (think about the fact that the square root of this is taken in the quadratic equation). So we can form the eq...
