x2 - 5x = 0x (x - 5) = 0x = 0andx = 5
x2 + 10x = 0 x2 + 10x + 25 = 25 (x + 5)2 = 25 x + 5 = +-5 x1 = 0 x2 =10
x2 - 10x + 25 = 0(x - 5)(x - 5) = 0x - 5 = 0x = 5
x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0
x2 + 10x = 18 x2 + 2(5)x - 18 = 0 x2 + 2(5)x + 25 = 18 + 25 (x + 5) 2 = 43 x + 5 = 430.5 x=6.56(3sf)-5
x2 + 2y = 52 + 2*2 = 25 + 4 = 29
if x2 = 5 the value of x has to be 5 divided by 2 which is 2.5 x = 2.5
x1:y1 = x2:y2 4:-2 = x2:5 x2 = (4*5)/-2 x2 = -10
Centre = (0,0), radius = sqrt(5)
2.5
-2-5
f(x) = x2 + 3 ----> f(5) = (5)2 + 3 ----> f(5) = 28
The vertex has a minimum value of (-4, -11)
To find p(x) / q(x), we first need to substitute the expressions for p(x) and q(x) into the formula. So, p(x) = 20x^5 - 20x^4 + 24x^2 and q(x) = 4x^2. Therefore, p(x) / q(x) = (20x^5 - 20x^4 + 24x^2) / 4x^2. Simplifying this expression, we get 5x^3 - 5x^2 + 6.
x2 - 5x = 0x (x - 5) = 0x = 0andx = 5
x = +5 or -5
Implicit: x2 + 2y = 5 Explicit : y = (5 - x2)/2
