Given:
2x² + 8x - 12 = 0
Solution:
The first term 2x² can't be changed to a complete square form. If we want to change it to the complete square form, we need to change 2x² to 4x². So, multiply both sides of the equation by 2
2x² + 8x - 12 = 0
------------------------- multiplied by 2
4x² + 16x - 24 = 0
then change it to complete quadratic form by adding 16 to both sides
4x² + 16x - 24 = 0
4x² + 16x + 16 - 24 = 16
4x² + 16x + 16 = 16 + 24
4x² + 16x + 16 = 40
(2x + 4)(2x + 4) = 40
(2x + 4)² = 40
This is the complete quadratic form of the equation.
Because there is no option of the solution, we can modify the equation by multiplying the two sides by a square number. I multiply the equation by 4.
(2x + 4)² = 40
4 (2x + 4)² = 4 × 40
4 (2x + 4)² = 160
4 (2x + 4)(2x + 4) = 160
2(2x + 4) 2(2x + 4) = 160
(4x + 8)(4x + 8) = 160
(4x + 8)² = 160
The answer is option b
The French had many alliances with the Indians and the British had more troops. The French has to deal with untrained troops.
Hope this helps :)
Answer:
<h2>AB = 38</h2><h2 />
Step-by-step explanation:
|<----------------- AB ------------------->|
A--------------------M--------------------B
5x + 4 3+16
since M is at midpoint, AM = MB
5x + 4 = 3 + 16
5x = 3 + 16 - 4
x = 15 / 5
x = 3
AB = AM + MB
AB = 5(3) + 4 + 3 + 16
AB = 15 + 23
AB = 38
Answer:
It's the y value of the point where the line intersects the y- axis.
Answer:
x = ?
Step-by-step explanation:
Equation written the right way:
d x (3 + x) = kx + 9d (-3 + x) = kx + 9d (-3 + x) = kx + 9
There is no steps or further way to find what x equals.
But above is the right way you should have typed it out and if anyone had figured out the answer, please put it in the comments.
