Identify coefficients: Identify the coefficients a, b, and c in the quadratic expression 2x2+5x+3. By comparing 2x2+5x+3 with the standard form ax2+bx+c, we find that a=2, b=5, and c=3.
Find two numbers: Find two numbers that multiply to a∗c (2∗3=6) and add up to b (5).We need to find two numbers that multiply to 6 and add up to 5. The numbers 2 and 3 fit this requirement because 2∗3=6 and 2+3=5.
Rewrite middle term: Rewrite the middle term 5x using the two numbers found in Step 2.We can express 5x as the sum of 2x and 3x. Therefore, we rewrite the expression as 2x2+2x+3x+3.
Factor by grouping: Factor by grouping.We group the terms as follows: 2x2+2x + 3x+3.Now we factor out the common factors from each group.From the first group, we can factor out 2x, giving us 2x(x+1).From the second group, we can factor out 3, giving us 3(x+1).
Write factored form: Write the factored form of the expression.Since both groups contain the factor (x+1), we can factor this out to get the final factored form of the expression: (2x+3)(x+1).
