The factoring is as follows: x2 - y2 = (x + y) * (x - y)
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
By factoring I get x-3 divided by x+3
3c(squared)-17c-6 = 0 (3c+1)(c-6) = 0 c= negative one third or positive 6
There is a formula for factoring the "difference of squares." In this case, the answer is (9 - 4x)(9 + 4x)
You can use the formula for factoring the difference of two squares in this case.
(x-12)2 using perfect square
Since the variable is the same, you can use the distributive property for this one. That is, subtract -8 minus 4, and attach the variable, "x", to the result.
The discriminant of this quadratic expression is less than zero therefore it cannot be factored.
(27 x 3) - (10 x 3) = 17 x 3 = 51
You look for a common factor between the two terms, take it out, and use the distributive property.
x3-x2 Both terms in this expression have x2 in them, so "divide" each term by it using the distributive property in reverse. x2(x-1) = x3-x2 If you "re-distribute" you should see that they are equal.
