Subtract the sum of a^2 − 2ab + b^2 and 2a^2 + 2ab + b^2 from the sum of a^2 − b^2 and a^2 + ab + 3b^2
solniwko [45]

Answer:

-a^2 + ab

Step-by-step explanation:

(a^2 - 2ab +b^2) + (2a^2 + 2ab + b2) = 3a^2 + 2b^2

(a^2 - b^2) + (a^2 + ab + 3b^2) = 2a^2 + 2b^2 + ab

subtract the first part from the second part:

(2a^2 + 2b^2 + ab) - (3a^2 + 2b^2) =    -a^2 + ab

Which is a reasonable first step that can be used to solve the equation 4 x + 3 (x + 2) = 5 (2 x minus 3)? Distribute the 3 to x
Mariana [72]

Answer:

Distribute the 3 to x + 2, and distribute the 5 to (2x – 3).

Step-by-step explanation:

Given

4x + 3(x + 2) = 5(2x - 3)

Required

Reasonable first step

The reasonable first step is to open the brackets; i.e. distribute 3 to its bracket and 5 to its bracket.

This gives:

4x + 3(x + 2) = 5(2x - 3)

4x + 3x + 6 = 10x - 15

<em>Then the solution can be continued</em>
