First notice I is the 2x2 identity matrix (1,0;0,1) now we can form an equation to solve for a, look for an entry where a is involved the (1,2) entry of I is 0 and calculated by 1(-1)+2a=0 now solving giv...

First differentiate the function with respect to x, dy/dx=6x+5 this finds the gradient function now calculate the gradient at point A by inputing x=2 into the gradient function 6(2)+5=17. Now using y=mx+c...

A monopoly is a type of market structure where by the market is dominated by one company. Due to the lack of participants in the market, the monopoly has the ability of charging high prices with low quant...

2x² + 6x + 62(x² + 3x + 3) => Factor out 4 from each term so the x² term of the quadratic has 1 for a coefficient.2[(x + 3/2)² - d + 3] => Here, we've div...

Firstly group the like terms to make the expression (5a+4a^2) and then factor out 'a' as it is a common term.This makes the expression ( a(5+4a))
