x2 + 4x - 60 factors into (x + 10)(x - 6). You can use the FOIL method to check your answers when you factor.
You will need to use the FOIL formula to solve this type of equation.
Method 1: 0.7+0.4+0.2=? 0.7+0.6=? 1.3(answer) Method 2: 0.7=7/10 0.4=4/10 0.2=2/10 (7+4+2)/10=13/10 or 1 3/10 or 1.3(answers)
To multiply two binomials you use FOIL (first, outer, inner, last): (y-9)(y+10)=y*y+10y-9y-9*10=y2+y-90
You will need to use the FOIL formula to write this problem and begin solving it for X.
