Question

(2a^2+a-3)-(3a^2+a-5)

Answer 1

Решение:
(2a² + а - 3) - (3a² + а - 5) =
2a² + а - 3 - 3a² - а + 5 =
(2a² - 3a² ) + ( - а + а) + (3 + 5) =
- a² + 2.
Ответ:
- a² + 2.

Answer 2

To subtract the expression (2a^2 + a - 3) from (3a^2 + a - 5), you simply combine like terms by subtracting the corresponding coefficients. Here's the step-by-step solution:

Step 1: Distribute the negative sign through the second expression: (3a^2 + a - 5) becomes -3a^2 - a + 5.

Step 2: Now, perform the subtraction by combining like terms: (2a^2 + a - 3) - (3a^2 + a - 5) = 2a^2 + a - 3 - 3a^2 - a + 5

Step 3: Group like terms together: = (2a^2 - 3a^2) + (a - a) + (-3 + 5)

Step 4: Perform the subtractions: = -a^2 + 0 + 2

Step 5: Simplify the final result: = -a^2 + 2

So, the simplified expression after subtracting (2a^2 + a - 3) from (3a^2 + a - 5) is -a^2 + 2.
