How do you factor d squared plus 4d plus 21?
That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: -2 plus or minus i times the square root of 17.x = -2 + 4.123105625617661ix = -2 - 4.123105625617661iwhere i is the square root of negative one.
How do you factor 12t squared minus t plus 4?
That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: (1 plus or minus the square root of -191) divided by 24t = 0.0416666 repeating + 0.5758447900452189it = 0.0416666 repeating - 0.5758447900452189iwhere i is the square root of negative one.
What are the factors of x2 6x 10?
That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: -3 plus or minus i, where i is the square root of negative 1.
What is the factorization to 7x squared minus 14x?
x2 - 2x - 14 doesn't factor neatly. Applying the quadratic formula, we find two real solutions: 1 plus or minus the square root of 15x = 4.872983346207417x = -2.872983346207417
How do you easily find the area of a circle?
3.14 times the radius SQUARED.
How do you factor x squared minus 2x minus 99?
Find factors of -99 which sum to -2. Solution appears to be 9 and -11 (x + 9)(x - 11)
How do you find the prime factors of a squared number?
The prime factors of a squared number are the prime factors, if any, of its square root.
How do you factor x squared minus 4x minus 5?
Find factors of -5 that can be added to make -4, in this case -5 and 1, so: (x - 5)(x + 1) = x2 - 4x - 5
How do you do pythagorean theorem when you have a and c?
B squared equals c squared minus a squared then to find B take the square root of you answer for b squared
How do you factor x squared minus 27x minus 58?
You try to find two factors of -58 whose sum is -27 .You find that -29 and +2 will do it, so . . .x2 - 27x - 58 = (x - 29) (x + 2)
How can pythagoream theorem be used to find a missing side length of a right triangle?
It can be found by: hypotenuse squared minus known side squared = unknown side squared
How do you find the b in the formula for area of a triangle?
The formula for finding the angles is called " Pythagorean Thyrum " It states that a squred plus b squared equals c squared so therefore c squared minus a squared will equal b squared. i hope that helps
X squared minus six x plus c find c?
there has to be more to the question is there a way you can tell what the equation equals
What is the length of the shorter leg of a right triangle if the longer leg has a length of 45 and the hypotenuse has a length of 53?
Subtract the squared longer leg's squared length from the hypotenuse's square to obtain the squared shorter leg length. Then find the square root of that answer for your final answer. In other words: 53 squared minus 45 squared equals your squared answer.
Find the length of a triangle?
a triangle has 3 sides. the longest side is always C. the other 2 are A and B (which one is which doesn't matter). u can find side C using A squared plus B squared equals C squared. It's basically AxA + BxB =CxC. to find side A, use C squared minus B squared. CxC - BxB = AxA . To find B, use the same equation to find A except switch B with A. CxC - AxA = BxB.-Mathnerd157
How do you factor x squared minus 2x plus 2?
That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: 1 plus or minus i where i is the square root of negative one.
