The product of two consecutive integers is 72. The equation x(x + 1) = 72 represents the situation, where x represents the smaller integer. Which equation can be factored and solved for the smaller integer?
x(x + 1) = 72 1) x²+x-72=0 - This equation can be factored. 2) (x+9)(x-8)=0 x=-9, x=8 3) If x=8, x+1=9 First number = 8 Second number = 9 4) If x=-9, x+1=-9+1=-8 First number = -9 Second number = -8
