Answer:
[tex]x^{2} + 3x - 28[/tex]
Step-by-step explanation:
FOIL Method:
1. Multiply the first values: (x * x) = [tex]x^{2}[/tex]
2. Multiply the outsides: (x * 7) = 7x
3. Multiply the inside values: (-4 * x) = -4x
4. Multiply the last values: (-4 * 7) = -28
5. Combine
You can combine 7x and -4x to get 3x, then write your answer in the standard layout.
