Answer 1

Answer:

(x+7)(x+9)

Step-by-step explanation:

x²+ 16x+63

x²+9x+7x + 7×9

x(x+9)+7(x+9)

(x+7)(x+9)

Answer 2

• As per the data given in the question, we have to determine the factor of the given quadratic equation.

        Given data:- $x^{2}+16x+63.$

        To find:- factor of given quadratic equation.

        Solution:-

        $\Rightarrow x^{2}+16x+63\\\Rightarrow x^{2}+9x+7x+63\\\Rightarrow x(x+9)+7(x+9)\\\Rightarrow (x+7)(x+9).$

      So, $x= -7$ and $x=-9.$

      Hence, the values of $x$ are $-7$ and $-9$ respectively.
