2.)which is a solution to the equation?
(x −2)(x + 5) = 18
x = −10

x = −7

x = −4

x = −2

Write the expression in simplified radical form. show all steps and work including any foil method work. (hint: use the conjugate. no decimal answers.) (9-2√3)/(12+√3)

Anyone know? is appreciated! will mark brainliest if correct!
