(−3y^2−7y−9)−(4y^2+6y+9). To solve this you must:
Distribute the negative sign like this:<span>
=<span><span><span><span>−<span>3y^2</span></span>−7y</span>−9</span>+<span>−1<span>(<span><span><span>4y^2</span>+6y</span>+9</span>)
</span></span></span></span><span>=<span><span><span><span><span><span><span><span>−<span>3y^2</span></span>+</span>−7y</span>+</span>−9</span>+<span>−1<span>(<span>4y^2</span>)</span></span></span>+<span>−1<span>(6y)</span></span></span>+<span><span>(−1)</span>(9)</span></span></span><span>
=<span><span><span><span><span><span><span><span><span><span><span>−<span>3y^2</span></span>+</span>−7y</span>+</span>−9</span>+</span>−<span>4y^2</span></span>+</span>−6y</span>+</span>−9
</span></span>Then combine Like Terms:<span>
=<span><span><span><span><span><span>−<span>3y^2</span></span>+<span>−7y</span></span>+−9</span>+<span>−<span>4y^2</span></span></span>+<span>−6y</span></span>+−9</span></span><span>
=<span><span><span>(<span><span>−<span>3y^2</span></span>+<span>−<span>4y^2</span></span></span>)</span>+<span>(<span><span>−7y</span>+<span>−6y</span></span>)</span></span>+<span>(<span>−9+−9</span>)</span></span></span><span>
=<span><span><span>−<span>7y^2</span></span>+<span>−13y</span></span>+−18
</span></span><span>So you would get an answer of </span>−7y^2−13y−18.
Hope this helped!
G = (-W+7)²
W = 7 -√G
W -7 = -√G
-W +7 = √G
(-W +7)² = G
