Question

Without actual division, show that (x^3 – 3x2 - 13x +15) is exactly
divisible by (x² + 2x - 3).​

Answer 1

Step-by-step explanation:

Area of Triangle : (Herons Formula)

√s(s-a)(s-b)(s-c)

where,

s = semi perimeter of Triangle

a,b,c = sides of triangle.

So,

Perimeter = 12+12+12 = 36

Semi Perimeter = 36/2 = 18

Putting the values,

√18(18-12)(18-12)(18-12)

√18 × 6 × 6 × 6

Area = 36√3 m²

Alternate Form:

62.35 m²
