STEP 1 - set the equations of the line and curve equal to each other STEP 2 - rearrange to quadratic form STEP 3 - find the discriminant and interpret its value Since the discriminant is zero, the line and the curve intersect at one point only Therefore the line is a tangent to the curve Unlock more, it's free!

Thus, to find the discriminant of a quadratic equation, follow the following steps: Step 1: Compare the given quadratic equation with its standard form ax 2 + bx + c = 0 and find the values of a, b and c Step 2: Substitute the values in the discriminant b 2 – 4ac to get the result

Quadratic Equation Formula can be derived from the steps for completing the square (actually, this formula is a general case) Let's see how to do it {a} { {x}}^ { {2}}+ {b} {x}+ {c}= {0} ax2 + bx +c = 0 { {x}}^ { {2}}+\frac { {b}} { {a}} {x}+\frac { {c}} { {a}}= {0} x2 + ab x + ac = 0

So the first thing I have to do is move the 1 over to the left-hand side of the equation, so I'll have " = 0 " on the right-hand side Doing so gives me the following equation: Letting a = 1, b = 2, and c = –1, the Quadratic Formula gives me: = \dfrac {-2 \pm \sqrt {4 + 4\,}} {2} = \dfrac {-2 \pm \sqrt {8\,}} {2} =2−2± 4+4 =2−2± 8

Given a quadratic equation: \[ax^2+bx+c = 0\] we can solve this equation for \(x\) using the following two steps: Step 1: calculate the discriminant, using the formula: \[\Delta = b^2 - 4ac\] Step 2: solve the quadratic equation, which depends on the sign of the discriminant \(\Delta\), which leads to three possible cases:

How to Calculate the Discriminant To calculate the discriminant of a quadratic equation, the formula is b 2 – 4ac Substitute the values of a, b and c after reading them from a quadratic equation of the form a𝑥 2 + b𝑥 + c For example, for 𝑥 2 – 3𝑥 + 4, a = 1, b = -3 and c = 4 b 2 = 9 and 4ac = 16 The discriminant, b 2

Answer: For getting proper understanding we have to follow following steps Step no 1: \(x^2 + 3x – 8 = 0\) (take a quadratic equation) Step no 2: Compare the equation with standard form \(ax^2 + bx + c = 0\) to get the values of a, b and c Step no 3: Find discriminant Δ \(Δ = b^2 – 4ac = (3)^2 – 4(1)(8) = 9 + 32 = 41\)
