It's a second degree trinomial expression in x. It's a perfect square, being the square of (x-2).
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.
(x-12)2 using perfect square
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)<-----
X= plus or minus 1
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)
9
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 square root of 28 minus the squared root of 7 =±2.64575131
The answer is 4, as 629 minus 4 equals 625. 625 is 25 squared.
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.
(x-12)2 using perfect square
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.
(x-1)(x-5)=x^2-6x +5 Because it is negative 5, I dont see an answer.
x2 + 8x - 9 = (x + 9)(x - 1)
5 squared is 25 4 squared is 16 25-16= 9 the square root of 9 is 3.
