 Calculate the discount amount:

Original Price - Selling Price = Discount

$1500 - $1200 = $300

(Discount / Original Price) * 100%

($300 / $1500) * 100%

0.20 * 100% = 20%

Explanation

Given:
$x^2 - 3x - 10 = 0$

We are told that one factor is $(x - 5)$.
So, we divide the quadratic by $(x - 5)$ to find the other factor:

Method:
Use factoring:

We want two numbers that multiply to $-10$ and add to $-3$.
These numbers are -5 and 2.

Thus,

$$x^2 - 3x - 10 = (x - 5)(x + 2)$$

Explanation

Given:

A sphere of radius 3 cm

Formula Used:

Total surface area of sphere = $4\times 22/7\times r^2$; where r = radius of sphere

Calculation:

⇒ Total surface area of sphere = $4\times 22/7\times 3^2$

⇒ Total surface area of sphere = $\frac{792}{7}=113.4{\text{cm}}^2\approx 113{\text{cm}}^2$

∴ required Total surface area of sphere = 113cm2
