Question

polynomial addition can be modeled using algebra tiles. what is the sum of the polynomial addition modeled by the algebra tiles? choose your answer: dropdown choose your answer: dropdown

Explanation:

Step1: Identify left polynomial

Count tiles: $2x^2 -5x -3$

Step2: Identify right polynomial

Count tiles: $4x^2 +6x$

Step3: Add like terms ($x^2$)

$2x^2 + 4x^2 = 6x^2$

Step4: Add like terms ($x$)

$-5x + 6x = x$

Step5: Add constant terms

$-3 + 0 = -3$

Step6: Combine all terms

$6x^2 + x - 3$

Answer:

$6x^2 + x - 3$
