WebCollecting like terms means to simplify terms in expressions in which the variables (usually letters) are the same. Two of the terms involve the variable \ (x\) and two involve the variable \ (y\). We can rearrange the expression so that the like terms are together: Now we can combine the \ (x\) terms and combine the \ (y\) terms: WebMultiply out the brackets and collect terms. Therefore the line \ (x = 1\) intersects the circle at \ ( (1, - 10)\). So it is a tangent. Again using the substitution method. Multiply out the brackets and collect terms. \ ( {b^2} - 4ac\) is negative, therefore there are no real roots. datetime month name c#
