The "solution" of an equation is the number that 'x' must be in order to make the
equation a true statement.
x2 + 8x + 20 is just a number, whose value depends on the value of 'x'. It's not
an equation, it asks no question, makes no statement, and poses no problem, so
it needs no answer, and there is nothing to "solve".
It can not be factored because its discriminant is less than zero
(4x + 1)(2x + 3)
x^2 +8x -9 is equivalent to (x+9)(x-1) when factored
(4x - 3)(2x + 3)
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
8x squared
When simplified it is: 1-8x
It is: 25+64 = 89
The given expression can be simplified to: 8x squared +9
It can not be factored because its discriminant is less than zero
(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
6x-20 = 8x 6x-8x = 20 -2x = 20 x = -10
-8x - 10 - 20 = -8x - 30
It is an expression that can be simplified to: -8x-4
5x+8x+3x-2x = 14x
4x+2<8x+20<4x 0<x x>0
7y+ 8x + 4= 20 + 8x- 8x - 8x7y + 4 = 20- 4 - 47y=16/7 /7y= 2.28the /7 means divide by 7 :)
