Q. Solve the quadratic by factoring.x2+3x+1=−1Answer: x=
Set Quadratic Equation Equal: First, we need to set the quadratic equation equal to zero by adding 1 to both sides of the equation.x2+3x+1+1=−1+1x2+3x+2=0
Find Two Numbers: Now, we need to find two numbers that multiply to give the constant term 2 and add to give the coefficient of the x term 3. The numbers that satisfy these conditions are 1 and 2 because: $1×2=21 + 2 = 3\)
Factor Quadratic Equation: We can now factor the quadratic equation using these two numbers.x2+3x+2=(x+1)(x+2)
Find Solutions: To find the solutions, we set each factor equal to zero and solve for x.First factor: x+1=0x=−1Second factor: x+2=0x=−2
