Find the solution of following equation (x+2)(x+3)=0 |
|
Answer» Answer: How do I solve Algebra Equation (x+2) (x+3)=0? This is a quadratic equation. Normally, you'll probably be given SOMETHING that looks like x^2 + 2x - 5 = 0. Then you'd have to factor the equation to solve. Here, you're lucky - it's already factored! That means we just need to set each of the two parts equal to zero, and solve each part. Remember you can have 2 answers to a quadratic equation! (x-2)(x+3) = 0 (x-2) = 0 OR (x+3)=0 x-2+2 = 0+2 OR x+3-3 = 0-3 x = 2 OR x = -3 this is already factored. use the zero product rule: if ab=0, then a=0, and b=0 therefore, if (x+2)(x+3)=0, let x+2=0, SUBTRACT 2 from each side, and x+2-2 = 0-2, and x = -2 then let the other factor equal 0: let x+3 =0, subtract 3 from each side, x+3-3 = 0-3 and. x = -3 therefore x = -2, and. x = -3 or (x+2)(x+3) - Original Equation x^2 + 2x +3x + 6 - FOIL x^2+5x+6 - Answer
If you are solving for X you have to isolate each factor and set it equal to 0
Solve the factor of (X+2) first x+2=0 (x+2) -2= 0-2 subtract 2 from both sides x = -2 answer
Now solve the factor of (x+3) (x+3) = 0 x+3-3= 0-3 subtract 3 from both sides x = -3 Answer
From the CALCULATIONS, you can see that x= -2 and -3. Step-by-step explanation: Hi ..... Hope it HELPS you..... Please mark me as Brillantiest |
