#x = -8, 7/2.#

If the product of two quantities is zero, then either of them is zero or both of them.

So, If #(x + 8)(2x - 7) = 0#,

Either #x + 8 = 0 rArr x = -8.#

Or, #2x - 7 = 0 rArr x = 7/2#

#x=-8" or "x=7/2#

#"equate each factor to zero and solve for x"#

#x+8=0rArrx=-8#

#2x-7=0rArr2x=7rArrx=7/2#

#rArrx=-8" or "x=7/2" are the solutions"#
