Q. Solve the quadratic by factoring.\newline5x2+11x+2=3x1 5 x^{2}+11 x+2=3 x-1 \newlineAnswer: x= x=
  1. Write Standard Form: Write the equation in standard form by moving all terms to one side of the equation.\newline5x2+11x+2=3x15x^2 + 11x + 2 = 3x - 1\newlineSubtract 3x3x from both sides and add 11 to both sides to get:\newline5x2+11x3x+2+1=05x^2 + 11x - 3x + 2 + 1 = 0\newlineCombine like terms:\newline5x2+8x+3=05x^2 + 8x + 3 = 0
  2. Identify aa, bb, cc: Identify aa, bb, and cc in the standard form of the quadratic equation ax2+bx+c=0ax^2 + bx + c = 0.\newlineIn the equation 5x2+8x+3=05x^2 + 8x + 3 = 0, we have:\newlinea=5a = 5\newlineb=8b = 8\newlinebb00
  3. Find Multiplying Numbers: Find two numbers that multiply to aca*c (53=155*3 = 15) and add up to bb (88).\newlineThe two numbers that satisfy these conditions are 55 and 33 because:\newline53=155 * 3 = 15\newline5+3=85 + 3 = 8
  4. Split Middle Term: Rewrite the equation by splitting the middle term using the two numbers found in Step 33.\newline5x2+5x+3x+3=05x^2 + 5x + 3x + 3 = 0\newlineGroup the terms:\newline(5x2+5x)+(3x+3)=0(5x^2 + 5x) + (3x + 3) = 0
  5. Factor by Grouping: Factor by grouping.\newlineFactor out the greatest common factor from each group:\newline5x(x+1)+3(x+1)=05x(x + 1) + 3(x + 1) = 0\newlineNow, factor out the common binomial factor (x+1)(x + 1):\newline(5x+3)(x+1)=0(5x + 3)(x + 1) = 0
  6. Set Factors Equal: Set each factor equal to zero and solve for xx.5x+3=05x + 3 = 0 or x+1=0x + 1 = 0For 5x+3=05x + 3 = 0:5x=35x = -3x=35x = -\frac{3}{5}For x+1=0x + 1 = 0:x=1x = -1
