Q. 0=3250x2 0=32-50 x^{2} \newlineWhat are the solutions to the given equation?\newlineChoose 11 answer:\newline(A) x=45 x=\frac{4}{5} \newlineB x=45 x=-\frac{4}{5} and x=45 x=\frac{4}{5} \newline(C) x=1625 x=\frac{16}{25} \newline(D) x=1625 x=-\frac{16}{25} and x=1625 x=\frac{16}{25}
  1. Given equation and type: Write down the given equation and identify the type of equation.\newlineThe given equation is 0=3250x20 = 32 - 50x^2. This is a quadratic equation in the form of ax2+bx+c=0ax^2 + bx + c = 0.
  2. Rearrange to standard form: Rearrange the equation to standard quadratic form.\newlineTo solve for xx, we need to rearrange the equation to the form ax2+bx+c=0ax^2 + bx + c = 0. In this case, we have:\newline50x2=3250x^2 = 32
  3. Isolate x2x^2: Divide both sides of the equation by 5050 to isolate x2x^2.\newlinex2=3250x^2 = \frac{32}{50}\newlinex2=0.64x^2 = 0.64
  4. Take square root: Take the square root of both sides to solve for x.\newlineSince x2=0.64x^2 = 0.64, we take the square root of both sides to find xx. Remember that taking the square root of both sides gives us two solutions: one positive and one negative.\newlinex=±0.64x = \pm\sqrt{0.64}\newlinex=±0.8x = \pm0.8
  5. Final solutions: Write down the final solutions.\newlineThe solutions to the equation are x=0.8x = -0.8 and x=0.8x = 0.8. These correspond to the choices (B) x=45x = -\frac{4}{5} and x=45x = \frac{4}{5}, since 0.80.8 is equivalent to 45\frac{4}{5}.
