Question

Find the remainder (without division) when
4x3 –3x2+2x-4 is divided by x+2​

Answer 1

Step-by-step explanation:

Suppose length of a side in the rhombus ABCD is a (AB=BC=CD=DA=a), then 4a=180 or a= 45 and the area is given by 0.5a^2sinABC=315 or sinABC=630/2025=14/45

The altitude = BC.sinABC=45.(14/45)=14

Hence answer is 14

Answer 2

x+2=0

x = -2

4x³ - 3x² + 2x - 4

p(x) = 4x³-3x²+2x-4

p(-2) = 4(-2)³-3(2)²+2×2-4

p(-2) = -32 - 12 +4-4

remainder = -64
