Full solution

Q. Factor.\newline3y2+7y+43y^2 + 7y + 4
  1. Identify coefficients: Identify the coefficients aa, bb, and cc in the quadratic expression 3y2+7y+43y^2 + 7y + 4 by comparing it to the standard form ax2+bx+cax^2 + bx + c.a=3a = 3b=7b = 7c=4c = 4
  2. Find two numbers: Find two numbers that multiply to aca*c (which is 34=123*4 = 12) and add up to bb (which is 77).\newlineThe two numbers that satisfy these conditions are 33 and 44 because:\newline3×4=123 \times 4 = 12\newline3+4=73 + 4 = 7
  3. Rewrite middle term: Rewrite the middle term 7y7y using the two numbers found in the previous step.3y2+7y+43y^2 + 7y + 4 can be rewritten as 3y2+3y+4y+43y^2 + 3y + 4y + 4.
  4. Group and factor: Group the terms into two pairs and factor by grouping.\newlineGroup (3y2+3y)(3y^2 + 3y) and (4y+4)(4y + 4).\newlineFactor out the greatest common factor from each group.\newlineFrom (3y2+3y)(3y^2 + 3y), factor out 3y3y: 3y(y+1)3y(y + 1).\newlineFrom (4y+4)(4y + 4), factor out 44: 4(y+1)4(y + 1).
  5. Notice common factor: Notice that both groups now contain the common factor (y+1)(y + 1).\newlineWrite the expression as the product of (y+1)(y + 1) and the other factors.\newlineThe factored form is (3y+4)(y+1)(3y + 4)(y + 1).
