Question 128185
{{{x^2+x-42=0}}}
Factor: (you will need to find two numbers that sum to 1 and multiply to -42
{{{(x - 6)(x + 7) = 0}}}
Solve for each factor:
{{{x - 6 = 0}}}
{{{x = 6}}}
{{{x + 7 = 0}}}
{{{x = -7}}}
Both x = 6 and x = -7 are solutions to this problem. (You will usually have two solutions to problems of this type.)
