Find the value or values of y in the quadratic equation y to the second power plus 4y plus 4 equals 7?
y^2 + 4y + 4 = 7
Hence
y^2 + 4y -3 = 0
Apply the Quadratic Eq'n
y = { - 4 +/- sqrt[(4)^(2) - 4(1)(-3)]} / 2(1)
y = { -4 +/- sqrt[ 16 + 12]} / 2
y = { 4 +/- sqrt(28)]}/ 2
y = {4 +/- 5.2915....} /2
y = 9.2915/// / 2 = 4.64575....
&
y = -1.2915... / 2 = -0.64575....

How do you use the quadratic formula to solve a quadratic equation?
You convert the equation to the form: ax2 + bx + c = 0, replace the numeric values (a, b, c) in the quadratic formula, and calculate.
How do you solve for x using a quadratic equation?
For an equation of the form ax² + bx + c = 0 you can find the values of x that will satisfy the equation using the quadratic equation: x = [-b ± √(b² - 4ac)]/2a
Find the value or values of x in the quadratic equation x2 equals 6x-9?
In the equation x2 = 6x - 9, all terms must be moved to one side of the equals sign, giving x2 - 6x + 9 = 0. This becomes factorable to (x -3)(x-3).
How do you solve 12x2-77x-20 equals 0 using quadratic formula?
-- First, write the quadratic formula on the back of your hand:x = 1/2A [ -B ± sqrt(B2 - 4AC) ]-- Then, stare at your equation until it dawns on you thatA = 12B = -77C = -20-- Substitute these values of 'A', 'B', and 'C' into the quadratic formula,evaluate it for the two values of 'x', and the two solutions practicallyfall out on the floor and surrender, on their own.
What is -22x equals -4xsquared plus 12?
It is a quadratic equation and the values of x are: -1/2 and 6
When solving a quadratic equation what do the X-values stand for as it relates to plotting the graph of the equation?
In a quadratic equation, the X-values represent the points where the graph of the equation intersects the X-axis, known as the roots or zeroes of the equation. These points indicate the values of X for which the quadratic expression equals zero. When plotted, these X-values help define the shape of the parabola, which can open upwards or downwards depending on the leading coefficient. The X-values also reflect the solutions to the equation when set equal to zero.
How do you make a table of values for a quadratic equation?
Simply learn and use the quadratic equation formula.
What is the solving for the roots of quadratic equation?
It is finding the values of the variable that make the quadratic equation true.

Equations 6-4x-3x² equals 0?
This is a quadratic equation requiring the values of x to be found. Rearrange the equation in the form of: -3x2-4x+6 = 0 Use the quadratic equation formula to factorise the equation: (-3x+2.69041576)(x+2.23013857) Therefore the values of x are 0.8968052533 or - 2.230138587 An even more accurate answer can be found by using surds instead of decimals.
What are you finding when you solve a quadratic equation?
You are finding the roots or solutions. These are the values of the variable such that the quadratic equation is true. In graphical form, they are the values of the x-coordinates where the graph intersects the x-axis.
