Basic MathElijah is building a deck. He has enough wood to build a 35 ft2 deck. Elijah wants
the deck to be 2 ft longer than it is wide. He sets up the following equations to
help him determine the dimensions of the deck.
x(x+2) = 35
x²+2x-35 = 0
where x is the width of the deck in feet.
How wide should Elijah make his deck? To solve for x, first factor the
left side of the equation. Note: The width of the deck must be positive.
Ignore negative values for x.
x = 7 feet
x = 3 feet
x = 5 feet
