First you must put everything to the left side, leaving only zero on the right. The original equation is:
x2 + 3x + 7 = 9
Subtract 9 on each side:
x2 + 3x - 2 = 0
This is the same as:
1x2 + 3x - 2 = 0
Therefore, the coefficients are: a = 1, b = 3, c = -2. Replace these in the quadratic equation.
Using the quadratic equation formula:- x = 3.795831523 or x = -5.795831523
Using the quadratic equation formula:- x = -4.706950048 and x = 0.849071913
A quadratic equation is univariate: it has only one variable. A quadratic equation cannot have two variables. So, if b and c are known then it is a quadratic equation in a; if a and b are known it is a quadratic in c.Another Answer:-The question given is Pythagoras' theorem formula for a right angle triangle
A quadratic equation.
Using the discriminant formula for a quadratic equation k has a value of 8/25 or maybe 0.
It is a quadratic equation and its solutions can be found by using the quadratic equation formula.
Using the quadratic equation formula: x = -5-/+ the square root of 7
Using the quadratic equation formula:- x = 3.795831523 or x = -5.795831523
The first step is to show an example of the quadratic equation in question because the formula given is only the general form of a quadratic equation.
y=b+x+x^2 This is a quadratic equation. The graph is a parabola. The quadratic equation formula or factoring can be used to solve this.
I suggest you use the quadratic formula. In this case, a = 1, b = 5, c = 3.
Using the quadratic equation formula:- x = -4.706950048 and x = 0.849071913
Without an equality sign the given expression can't be considered to be an equation but if it equals 0 then using the quadratic equation formula will give its solutions.
A quadratic equation is univariate: it has only one variable. A quadratic equation cannot have two variables. So, if b and c are known then it is a quadratic equation in a; if a and b are known it is a quadratic in c.Another Answer:-The question given is Pythagoras' theorem formula for a right angle triangle
No. It is a quartic equation. The largest power of x in a quadratic equation must be 2.
x2+11x+11 = 7x+9 x2+11x-7x+11-9 = 0 x2+4x+2 = 0 The above quadratic equation can be solved by using the quadratic equation formula and it will have two solutions.
Use the quadratic formula, with a = 1, b = -3, c = 2.
