Answer:

x=5 or x=3

Explanation:

The first step is to factor:
#x^2 - 9x + 20 = 0 #
#(x-5) (x-4) = 0#

The second step is to set each factor to zero:
#x=5# or #x=3#

Answer:

#x=4# or #x=5#

Explanation:

The first step when solving for solutions is to factor the equation:
#x^2-9x+20=0#, which when factored will be: #(x-4)(x-5)=0#

The next step is to solve each for zero:
#(x-4)(x-5)=0#
#x=4# or
#x=5#
