add/sub polynomials Matching
1.(-2t-7)+(-t+2)
2.(5s +3t+9)-(25-t-1)​

Answer 1

symbol. For example, to express x2, enter x^2. Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not currently be placed 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5). The * is also optional when multiplying with parentheses, example: (x + 1)(x - 1).

Answer 2

Answer:

Addition

$( - 2t - 7) + ( -t + 2)$

$- 2t - 7 - t + 2$

$- 2t - t - 7 + 2$

$- 3t - 5$

Subtracting

$(5s +3t+9)-(25-t-1)$

$5s + 3t + 9 -25 + t + 1$

$5s + 3t + t + 9 + 1 - 25$

$5s + 4t + 10 - 25$

$5s + 4t - 15$
