Write the following square of binomial as trinomial: (x + 2)2
Advertisements
उत्तर
We will use the identities
\[\left( a + b \right)^2 = a^2 + 2ab + b^2 \text { and } \left( a - b \right)^2 = a^2 - 2ab + b^2\] to convert the squares of binomials as trinomials.
\[\left( x + 2 \right)^2 \]
\[ = x^2 + 2 \times x \times 2 + b^2 \]
\[ = x^2 + 4x + b^2\]
