- Simplify :- 1 + - w² + 9w.
Quadratic polynomial can be factored using the transformation , where are the solutions of the quadratic equation .
All equations of the form can be solved using the quadratic formula: . The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.
Square 9.
Multiply -4 times -1.
Add 81 to 4.
Multiply 2 times -1.
Now solve the equation when ± is plus. Add -9 to .
Divide -9+ by -2.
Now solve the equation when ± is minus. Subtract from -9.
Divide by -2.
Factor the original expression using . Substitute for and for .
<h3>NOTE :-</h3>
Well, in the picture you inserted it says that it's 8th grade mathematics. So, I'm not sure if you have learned simplification with the help of biquadratic formula. So, if you want the answer simplified only according to like terms then your answer will be ⇨
This cannot be further simplified as there are no more like terms (you can use the biquadratic formula if you've learned it.)

Answer:
8,000
Step-by-step explanation:
volume = length X width X height
5x20x40= 4000
4000x2 = 8000
Answer:
x =112
Step-by-step explanation:
The sum of the angles of a triangle add to 180
Two angles are 34 and 34. Let the third angle be x
34+34+x = 180
Combine like terms
68+x = 180
Subtract 68 from each side
68-68 +x = 180-68
x =112
Answer:
the force that must be applied by the driver to release the clutch is 21 lb
Step-by-step explanation:
Data provided:
clutch linkage on a vehicle has an overall advantage = 24:1
Applied force by the pressure plate = 504 lb
Now,
the advantage ratio is given as:
advantage ratio =
on substituting the respective values, we get
=
or
Force applied by the driver to release the clutch =
or
Force applied by the driver to release the clutch = 21 lb
Hence,
the force that must be applied by the driver to release the clutch is 21 lb
