Question

(3t+2) (3t+1) find the product

Answer 1

Answer:

9t^2+9t+2 is the answer

Answer 2

Answer:

(3t)²+ (2+1)3t + 2×1

=9t² + 9t + 2

Step-by-step explanation:

• We used the Identity 4 for this sum.
•  Identity 4 is (x+a)(x+b) = x² +(a+b) × x + ab.
• In this x = 3t , a=2 , b=1.
• Then the equation will be (3t+2) (3t+1)= (3t)² + (2+1)3t + 2×1.
• This equals to 9t² + 9t + 2 which will be the final answer as we cant simplify it anymore.
