Since its already factored, use the Zero Product Property to solve.
Factor out a 2 from the equation, then factor the quadratic.
Once factored, see part (a).
Multiply throughout by 2 to remove the decimals.
Factor and use the Zero Product Property to solve.
(x + 3)(x + 3) = 0
x = −3
Subtract 14 from both sides, then factor.
Once factored, see parts (a) and (c) for more help.
x = 2 or −7
