Question

solve this equation:

x^2- 15x- 16=0​

Answer 1

Answer:

-1,16

Step-by-step explanation:

x²-16x+x-16=0

x(x-16)+1(x-16)=0

(x+1)(x-16)=0

x=-1,16

Answer 2

Answer:

x square - 15x - 16 = 0

x square -16x + x -16 = 0..... 16 x 1 = 16 and -16 + 1 = -15

x( x - 16 ) + 1( x - 16)

Therefore, ( x-16) Or (x + 1)

x - 16 = 0 or x + 1 = 0

x = 16 or x = -1

are the roots of the following quadratic

equation.
