Factorise. 3x2+5x+2=03x^{2}+5x+2=0

Full solution

Q. Factorise. 3x2+5x+2=03x^{2}+5x+2=0
  1. Write Quadratic Equation: Write down the quadratic equation to be factorized.\newline3x2+5x+2=03x^2 + 5x + 2 = 0
  2. Find Two Numbers: Look for two numbers that multiply to give the product of the coefficient of x2x^2 (which is 33) and the constant term (which is 22), and add up to give the coefficient of xx (which is 55).\newlineThe numbers we are looking for are 33 and 22 because 3×2=63 \times 2 = 6 and 3+2=53 + 2 = 5.
  3. Rewrite Middle Term: Rewrite the middle term 5x5x using the two numbers found in Step 22. 3x2+3x+2x+2=03x^2 + 3x + 2x + 2 = 0
  4. Factor by Grouping: Factor by grouping. Group the first two terms together and the last two terms together.\newline(3x2+3x)+(2x+2)=0(3x^2 + 3x) + (2x + 2) = 0
  5. Factor Out Common Factor: Factor out the common factor from each group.\newline3x(x+1)+2(x+1)=03x(x + 1) + 2(x + 1) = 0
  6. Final Factorization: Since both groups contain the common factor (x+1)(x + 1), factor this out.(3x+2)(x+1)=0(3x + 2)(x + 1) = 0
