<h3>What is engineering notation ?</h3>

Engineering notation is same as scientific notation.

According to the given question

Converting (8.2 × 103) × (5.0 × 104) to engineering notation can be done using a base and raising it to the power of 10.

Base can be greater than or equal to 1 and less than 10.

Suppose base is a

∴ 1≤a<10 and the number in engineering notation will be of the form a×10ⁿ

Given (8.2 × 103) × (5.0 × 104) which is

Answer:

\boxed{2\pm \frac{\sqrt{2}}{2}}

Step-by-step explanation:

2x^2-8x=-7

\sf Add \ 7 \ on \ both \ sides}.

2x^2-8x+7=-7+7

2x^2-8x+7=0

ax^2 +bx+c=0

\sf Apply \ quadratic \ formula.

a=2 \ \ \  b=-8 \ \ \ c = 7

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

x=\frac{-(-8)\pm\sqrt{(-8)^2-4(2)(7)}}{2(2)}

x=\frac{8\pm\sqrt{64-56}}{4}

x=\frac{8\pm\sqrt{8}}{4}

x=\frac{8\pm2\sqrt{2}}{4}

x=2\pm \frac{\sqrt{2}}{2}
