Question

solve the quadratic equation by factorization method. x square- 16 X + 63 equals to zero​

Answer 1

Answer:( x − 7 ) ( x − 9 ) = 0  

Explanation: In general:

( x − a ) ( x − b ) = x 2 − ( a + b ) + a b

We find  63 = 7 × 9  and  16 = 7 + 9 , so:

x 2 − 16 x + 63 = ( x − 7 ) ( x − 9 )

Answer 2

Step-by-step explanation:

x x square - 16 + 63 is equal to zero
