Question

Subtract: 6a3 - 2a2 + 4 from 5a3 - 4a + 7

Answer 1

subtract like terms

5a^3 - 6a^3 = -a^3

7 - 4 = 3

answer is -a^3 + 2a^2 - 4a + 3

Answer 2

Answer:

$-1a^3+2a^2-4a+3$

Step-by-step explanation:

Subtract:$6a^3 - 2a^2 + 4$ from $5a^3 - 4a + 7$

$(5a^3-4a+7)-(6a^3-2a^2+4)$

To subtract multiply the negative sign inside the parenthesis and combine like terms

$5a^3-4a+7-6a^3+2a^2-4$

Combine the like terms

$5a^3-6a^3= -1a^3$, 7-4=3

No like terms for -2a^2 and 4a. so it remains the same

$5a^3-4a+7-6a^3+2a^2-4$

$-1a^3+2a^2-4a+3$
