Answer:
x = - 5
x = 6
Explanation:
x^2 - 30 = x
move terms to the left side
x^2 - 30 - x = 0
rearrange terms
x^2 - x - 30 = 0
use sum-product method
x^2 - 6x + 5x - 6*5 = 0
write in factor form
x(x-6) +5(x-6) = 0
(x+5)(x-6) = 0
set each factor to zero
x + 5 = 0
x - 6 = 0
raarrange it
x = - 5
x = 6
answer
x = - 5
x = 6
