#x = -7# and #x = -7/2#

#(x+7)(2x+7) = 0#

We set each of the things inside the parentheses to 0, like this:

#x + 7 = 0# and #2x + 7 = 0# and solve for each of them:

#x = -7# and #2x = -7#

#x = -7# and #x = -7/2#

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

#"the equation is given in factored form hence"#

#"equate each of the factors to zero and solve for x"#

#x+7=0rArrx=-7#

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