They are all direct variations
B.
------------------------------------
3.1 Solve<span> : </span>4x2<span>+3 = 0. Subtract 3 from both sides of the equation : </span><span>4x2 = -3</span>. Divide both sides of the equation by 4: x2<span> = -3</span>/4 = -0.750. When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get: x = ± √ -3/4. In Math, i is called the imaginary unit. It satisfies i 2<span> =-1.</span>
