Three less than twice a number is equal to the number?
Suppose you start with x. Twice x is 2x. Three less than that is 2x-3 So 2x-3 = x Add 3 to both sides: 2x = x + 3 Subtract 1x from both sides: x = 3. You started with 3.
Factor 2x squared plus 5x plus 3?
2x2 + 5x + 3 Notice the first term, which can be rewritten as 2x times x. With this in mind, you can write the equation as...(2x + a)(x + b)...where -a and -b are the answers.You know that a times b is equal to 3.With a little trial and error, you will find:2x2 + 5x + 3 = (2x + 3)(x + 1)
