2(x^2 - 8)

It is: 5(x^2 -16)

It is the difference of squares. (x-4) and (x+4) <--- answer

x2 - y2 = 16 then (x + y)*(x - y) = 16 This has an infinite number of solutions lying on the hyperbola.

It can't be factored because its discriminant is less than zero.

62 - 16 = 20

14x2-7x2-16 7x2-16 (this can't be simplified any more)

75r^2-48 You can take out 3.So... 3(25r^2-16) 3-parenthesis-25r squared-minus-16-parenthesis (:

(b-4) squared

9x squared plus 16 = 0 factored is plus and minus 4/3 i.

Pull out the common factor of 2 ... 2(y^2+6y-16) Then just factor (y^2+6y-16) ... (y-2)(y+8)

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.

9x squared plus 16 = 0 factored is plus and minus 4/3 i.

81 x 2 - 16 = 146

(4x-8)(2x+2)

x-8

If the question could more exactly be phrased as, "What is the value of x when 9x2 - 16 = 0", the answer is, x = 4 or -4. This answer can be found by factoring 9x2 - 16 into (3x + 4)(3x - 4) and setting each factor equal to zero.

(x - 16)(x + 2) x = 16 or -2

5 squared is 25 4 squared is 16 25-16= 9 the square root of 9 is 3.

4 squared is 16. 4 squared means that 4 is used as a factor 2 times. 4x4=16

In one bracket, write 16 times the square root of 2 minus 3x. In the other one, write 16 times the square root of 2 plus 3x.

Two plus 3 minus 2 times 1 squared plus 4 times 16 squared minus 4 times 2 is equal to 1,019.

(3x-4)(3x+4)

Without any parenthesis is: 92 - 2 * 15 + 16 - 8 = 59

(y - 8)(y - 2)
