Step 1: Rearrange equation to form x2 + bx + c= 0 -Add 10 to both sides of equation: x2-7x +10=0 Step 2: Factorise the quadratic equation -Find tw...
Write 2x2+ 12x + 3 in the form p(x + q)2+ r Step 1: Factorise all the x terms using a common factor with brackets. In this case 2 is a common factor to both 2x2and 12x ===...
Using the sum rule, you can split the function in three terms and then derive each of them separately. The rule is to bring down the power and the power minus one. So for the first term, it becomes 2*4xAnswered by Yanni C. • Maths tutor3069 Views
To show that the line is a diameter of the circle you muct show that it goes through the centre of the circle1) finding the centre of the circle. The general eqn is (x-a)2 + (y-b)2 =...
At any stationary point, the gradient of a line is zero. Therefore dy/dx = 0. If we differentiate the equation of the line, and solve this expression we can find the coordinates of the stationary po...
