Expand (x + 5)(x − 5)
Worked out line by line the way a teacher would write it.
Answer
| Expanded form | x² − 25 |
Step-by-step solution
3 steps-
1 Given\left(x + 5\right) \left(x - 5\right)
-
2 Multiply the binomials (FOIL: First, Outer, Inner, Last)
To multiply two binomials, multiply every term of one by every term of the other: the First terms, the Outer terms, the Inner terms and the Last terms, four products in all.
\left(x \cdot x + x \cdot 5 + (-5) \cdot x + (-5) \cdot 5\right) -
3 Multiply out and combine like termsx^{2} - 25
