Answer:
1.4
Step-by-step explanation:
X^4+ 3x^3+4x^2-8 | x+2 = x^3+x^2+2x-4
-x^4-2x^3
-----------------------
x^3+4x^2-8
-x^3-2x^2
-------------------------
2x^2-8
-2x^2-4x
--------------
-4x-8
4x+8
----------------------------
/ /
is a factor because (x+2)(x^3+x^2+2x-4)=x^4+3x^3+4x^2-8
Answer :
To find the product of (x + 8)(x – 10)
We know that
(x + a)(x + b) = x2 + (a + b)x + ab
In the expression (x + 8)(x – 10)
a = 8
b = -10
a + b = 8- 10 = -2
ab = 8 × (-10) = – 80
Substitute the values in the above equation
(x + 8)(x – 10) = x2 + (8 – 10)x + 8 × (-10)
(x + 8)(x – 10) = x2 – 2x – 80.
