Q. Solve the quadratic by factoring.x2+4x+32=−8x−3Answer: x=
Write Equation and Rearrange: Write down the given equation and move all terms to one side to set the equation to zero.x2+4x+32=−8x−3Add 8x to both sides and add 3 to both sides to get:x2+12x+35=0
Identify Coefficients: Identify a, b, and c in the quadratic equationax2+bx+c=0. Here, a=1, b=12, and c=35.
Find Multiplying Numbers: Find two numbers that multiply to ac (which is 35) and add up to b (which is 12).The numbers 5 and 7 multiply to 35 and add up to 12.5×7=355+7=12
Split Middle Term: Write the quadratic equation with the middle term split using the two numbers found in Step 3. x2+5x+7x+35=0
Factor by Grouping: Factor by grouping.Group the terms to factor out the common factors:x(x+5)+7(x+5)=0
Factor out Common Factor: Factor out the common binomial factor. x + \(5)(x + 7) = 0\
Set Factors Equal and Solve: Set each factor equal to zero and solve for x.x+5=0 or x+7=0x=−5 or x=−7
