Full solution

Q. Factor.\newline9t2+12t+49t^2 + 12t + 4
  1. Check Factoring Possibility: Determine if the quadratic expression can be factored using the form (at+b)2=a2t2+2abt+b2(at + b)^2 = a^2t^2 + 2abt + b^2. The given expression is 9t2+12t+49t^2 + 12t + 4. We need to check if there are numbers aa and bb such that (at+b)2(at + b)^2 matches the given expression.
  2. Identify Square Roots: Identify the square root of the first term and the last term.\newlineThe square root of 9t29t^2 is 3t3t, and the square root of 44 is 22. So, we will check if (3t+2)2(3t + 2)^2 equals the given expression.
  3. Expand and Verify: Expand (3t+2)2(3t + 2)^2 to verify if it equals the given expression.(3t+2)2=(3t+2)(3t+2)=9t2+6t+6t+4=9t2+12t+4(3t + 2)^2 = (3t + 2)(3t + 2) = 9t^2 + 6t + 6t + 4 = 9t^2 + 12t + 4 This matches the given expression exactly.
  4. Write Factored Form: Write the factored form of the expression.\newlineSince (3t+2)2(3t + 2)^2 equals the given expression, the factored form is (3t+2)(3t+2)(3t + 2)(3t + 2) or (3t+2)2(3t + 2)^2.
