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
