It's a second degree trinomial expression in x. It's a perfect square, being the square of (x-2).
2(5x + 7)(x - 5)
To factor a trinomial square take the square roots of the end terms and join them with a plus sign if the middle term is preceded by a plus or with a minus if the middle term is preceded by a minus.
The square root of 28 minus the squared root of 7 =±2.64575131
Remember to factor out the GCF of the coefficients if there is one. A perfect square binomial will always follow the pattern a squared plus or minus 2ab plus b squared. If it's plus 2ab, that factors to (a + b)(a + b) If it's minus 2ab, that factors to (a - b)(a - b)
The answer is 4 squared minus 2 squared as 4 squared is 16 minus 2 squared, which is 4, gives you 12 as an answer.
The answer is 4, as 629 minus 4 equals 625. 625 is 25 squared.
(x-12)2 using perfect square
5 squared is 25 4 squared is 16 25-16= 9 the square root of 9 is 3.
This is when two perfect squares(ex.) [x squared minus 4] a question in which there are two perfect squares. you would find the square root of each. then it depends on what kind of math your doing.
4 squared minus 2 squared equals 12
B squared equals c squared minus a squared then to find B take the square root of you answer for b squared
x2 + 8x - 9 = (x + 9)(x - 1)
(x-1)(x-5)=x^2-6x +5 Because it is negative 5, I dont see an answer.
square root of 8
(x squared plus the square root of 2) times (x squared minus the square root of 2).
X= plus or minus 1
2m^2 - 8 -First you should factor out a two. --> 2(m^2-4) -You now have something squared minus something else squared; You have m squared minus 2 squared. Whenever you have something squared minus something squared as you do in this case, there is a simple rule to remember: You can reduce that expression into the quantity of the square root of the first number or variable plus the square root of the second number or variable Times the quantity of the square root of the first number or variable minus the second number or variable squared. --> In the case of your expression: ----> 2(m+2)(m-2)<-----
n squared minus n
2x squared minus 4
3x squared minus 25x minus 28
Complete the square or use the quadratic formula.
still 1The square root of 1 is plus or minus 1. √1 = ± 1 The reason is that 12 = 1 and -12 = 1. (Either 1 squared or minus 1 squared equals one.)
If x squared -10 = 0 then x = the square root of 10
