subtract as indicated 1. (b - 7) - (4b - 2) = 2. (2x² - 3y) - ( 3x² - 5y)= 3.(10 - 4x - 2) - (3 + 6x -2x²) = (pa help pleasee)​

Answer:

1.Simplify

Let's simplify step-by-step.

b−7−(4b−2)

Distribute the Negative Sign:

=b−7+−1(4b−2)

=b+−7+−1(4b)+(−1)(−2)

=b+−7+−4b+2

Combine Like Terms:

=b+−7+−4b+2

=(b+−4b)+(−7+2)

=−3b+−5

Answer:

=−3b−5

2.

Simplify

Let's simplify step-by-step.

2x2−3y−(3x2−5y)

Distribute the Negative Sign:

=2x2−3y+−1(3x2−5y)

=2x2+−3y+−1(3x2)+−1(−5y)

=2x2+−3y+−3x2+5y

Combine Like Terms:

=2x2+−3y+−3x2+5y

=(2x2+−3x2)+(−3y+5y)

=−x2+2y

Answer:

=−x2+2y

3.

Simplify

Let's simplify step-by-step.

10−4x−2−(3+6x−2x2)

Distribute the Negative Sign:

=10−4x−2+−1(3+6x−2x2)

=10+−4x+−2+(−1)(3)+−1(6x)+−1(−2x2)

=10+−4x+−2+−3+−6x+2x2

Combine Like Terms:

=10+−4x+−2+−3+−6x+2x2

=(2x2)+(−4x+−6x)+(10+−2+−3)

=2x2+−10x+5

Answer:

=2x2−10x+5
