Answer 2

Answer:

The answer is x^2 +14x + 49

Step-by-step explanation:

By multiplying systematically,

$(x + 7)(x + 7) \\ = x(x + 7) + 7(x + 7) \\ = {x}^{2} + 7x + 7x + 49 \\ = {x }^{2} + 14x + 49$

Or you can use the formula for

${(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2}$

Here a=x and b=7

By this way too the answer comes out to be

${x}^{2} + 14x + 49$
