Answer 2

Hi friend The answer is given below ,

$\big\langle\Big\langle\bigg\langle\Bigg\langle \LARGE\;\underbrace{\underline{\sf{Understanding\ the\ question\big\rangle\Big\rangle\bigg\rangle\Bigg\rangle}}}$

The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.

Solving Quadratic Equations

1. Put all terms on one side of the equal sign, leaving zero on the other side.
2. Factor.
3. Set each factor equal to zero.
4. Solve each of these equations.
5. Check by inserting your answer in the original equation.

★ Solution :-

$2x^{2} +x-6=0\\2x^{2}+4x-3x-6=0\\2x(x+2)-3(x+2)=0\\(2x-3)(x+2)=0x=3/2;-2$

hence the answer is (i) x-3/2

I am pretty sure it will help you in equation
