Answer 1

Quadratic equations are equation that has degree of 3. The value of x from the quadratic equation is 3

Factorizing the quadratic equation

Quadratic equations are equation that has degree of 3. Given the following equation;

5x²-11x = 1

Equate to zero

5x²-11x - 1 = 0

Find the solution using quadratic solution

$x=\frac{11\pm\sqrt{121-4(5)(-1)}}{2(5)}\\x=\frac{11\pm\sqrt{141} }{10} \\x=\frac{11\pm11.87 }{10} \\x=\frac{22.87}{18}\\ x\approx 3$

Hence the value of x from the quadratic equation is 3
