Question

solve the following quadratic equation by using formula x^2-6x=27​

Answer 1

Answer:

x²-6x=27

x²-6x-27=0

x²-(9-3)x-27=0

x²-9x+3x-27=0

x(x-9)+3(x-9)=0

(x+3)(x-9)=0

x+3=0 x-9=0

x=-3 x=9 ANSWER

Answer 2

x^2 - 6x = 27

x^2 - 6x - 27 = 0

x^2 - 9x + 3x - 27 = 0

x(x - 9) +3(x - 9) = 0

(x - 9)(x + 3) = 0

x = 9 & x = -3
