10 to the third power is 1000
X^2 - 14 x = 15
(x - 7)^2 - 49 = 15
(x-7)^2 = 64
x - 7 = - or + 8
x = 15 or -1
Just take half o the coefficient of x and subtract it squared as above.
In general
x^2 + ax = b
(x + a/2)^2 - a^2/4 = b

Answer:
12 square feet
Step-by-step explanation:
You can find out how many square feet he bought by dividing 432 by 3.
