Answer

x=12,x=3x = \frac{1}{2}, x = -3

Step 1: Identify the equation to be solved. The equation is 2x2+5x3=02x^2 + 5x - 3 = 0.

Step 2: Use the quadratic formula to solve for xx. The quadratic formula is x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}. In this equation, a=2a=2, b=5b=5, and c=3c=-3.

Step 3: Substitute the values of aa, bb, and cc into the quadratic formula. x=5±524(2)(3)2(2)x = \frac{-5 \pm \sqrt{5^2 - 4(2)(-3)}}{2(2)}

Step 4: Simplify the expression under the square root. x=5±25(24)4x = \frac{-5 \pm \sqrt{25 - (-24)}}{4} x=5±25+244x = \frac{-5 \pm \sqrt{25 + 24}}{4} x=5±494x = \frac{-5 \pm \sqrt{49}}{4}

Step 5: Calculate the square root. x=5±74x = \frac{-5 \pm 7}{4}

Step 6: Solve for the two possible values of xx. For the '+' case: x1=5+74=24=12x_1 = \frac{-5 + 7}{4} = \frac{2}{4} = \frac{1}{2} For the '-' case: x2=574=124=3x_2 = \frac{-5 - 7}{4} = \frac{-12}{4} = -3

The solutions are x=12x = \frac{1}{2} and x=3x = -3.

x = \frac{1{2}, x = -3}
