Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)
It is a binomial expression.
The general expression for a quadratic polynomial is: ax2 + bx + cComparing x2 - 4x - 45 with general expression we geta = 1, b = -4 and c = -45Multiplying a and c: ac = -45Now break down b in two numbers in such a way that sum of the numbers is -4 and product is equal to -45, product of a and c.The two numbers are -9 and 5. Since sum of -9 and 5 is -4 and the product is -45.So in place of -4x we can write -9x + 5x.The expression now becomes: x2 - 9x + 5x - 45x(x - 9) + 5(x - 9)(x + 5)(x - 9)So factors are (x + 5) and (x - 9).Note: The middle term is split into two terms so that there are in total four terms in the expression and the product of extreme terms is equal to product of middle terms.
82y 16x are both not equal to the given expression.
The value of the expression x2 + 9 will depend on what value you plug in for x. If you are looking to factor that expression, it can only be done using complex numbers:x2 + 9 = (x + 3i)(x - 3i)
If you mean: 4x-87x+9 then the expression can be simplified to: 9-83x
Oh, dude, that's easy! So, if we're talking about an expression like x < 9, it just means that x is smaller than 9. Like, imagine 9 is the cool kid at the party, and x is just trying to hang out but isn't quite as popular. So yeah, x is definitely less than 9 in this case.
83 x 30 x 35 is equal to 87,150.
74 X 83 = 6142.
x+x+9=83 2x=83-9=74 x=37 boy+37

Let's say x is your "number" Remember, expressions do not have equal signs. If something in algebra has an equal sign, t is called an equation. (x/9) +5 would be your answer. Remember p.e.m.d.a.s. if asked to use that expression.
