I think it’s 28.35

54/100 x 5 = 2.7
54 + 2.7 = 56.7
56.7/100 x 50 = 28.35
56.7 -28.35 = 28.35

Solve this equation using all three methods 4x^ = 9

Bumek [7]

Answer:

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

Step-by-step explanation:

(1) To solve by factoring,

Given equation: $4 x^{2}=9$

Subtract 9 from both sides of the equation.

$\begin{aligned}&4 x^{2}-9=9-9\\&4 x^{2}-9=0\\&(2 x)^{2}-3^{2}=0\\&(2 x-3)(2 x+3)=0\end{aligned}$

Using zero factor principle, $2 x-3=0,2 x+3=0$

The solutions are $x=-\frac{3}{2}, x=\frac{3}{2}$ .

(2) To solve by complete the square ,

Given $4 x^{2}=9$

Divide both sides of the equation by 4.

$\frac{4 x^{2}}{4}=\frac{9}{4}$

$\Rightarrow x^{2}=\frac{9}{4}$

Square root on both sides.

$\Rightarrow x=\pm \frac{3}{2}$

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

(3) To solve by quadratic formula,

$4 x^{2}-9=0$

Here, a = 4, b = 0, c = –9

Quadratic formula, $x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

$x=\frac{-0 \pm \sqrt{0^{2}-4 \times 4 \times(-9)}}{2 \times 4}$

$\begin{aligned}&\Rightarrow x=\frac{\pm \sqrt{144}}{8}\\&\Rightarrow x=\pm \frac{3}{2}\\&\Rightarrow x=\frac{3}{2}, x=-\frac{3}{2}\end{aligned}$
