Start off by dealing with the brackets by expanding. The brackets around a part of the equation imply that the entire content of the brackets will be affected by the factor outside of the brackets, in thi...

SUVAT equations link the variables S (displacement), U (initial speed), V(final speed), A(accelerations), and T (time), for situations where there is constant acceleration. Each of the 5 SUVAT equations ...

Since there is only two terms it is a case of seeing what both terms have in common. Both share a 2 and an x so having this an the coefficient to the bracket gives 2x(x-7)

To begin with it is important to identify which method of differentiation is required here, since there are two terms multiplied together you would initially choose the product rule, differentiating (4x-3...

'No Nonsense' Answer: Our equation is x^2 - 2x - 15 = 0 so we want to find two numbers that add to get -2 and multiply to get - 15. The possible numbers pairs that multiply to get -15 are...1 and -15, -1 ...
