By the remainder theorem the remainder when dividing p(x) by x-a is p(a).
Dividing by x+1 means we want p(-1).
p(-1) = (-1)³ - 2(-1)² -4(-1) - 1 = -1 - 2 + 4 - 1 = 0
Answer: 0
They go in evenly so x+1 is a factor of p(x).
Answer:
<h2>(-1, 17)</h2>
Step-by-step explanation:
The vertex form of a quadratic equation:
<em>(h, k)</em> - vertex
<em>use (a + b)² = a² + 2ab + b² </em><em>(*)</em>
<em>h = -1, k = 17</em>
Value of x is 2 and y is 0 of the equations 2x + y = 4 and x - y = 2.
<h3>Define equation.</h3>
A mathematical expression with an equals sign is referred to as an equation. Algebra is widely used in equations. When performing calculations but unsure of the precise amount, algebra is used.
Given,
Equation:
2x + y = 4
x - y = 2
From equation 2,
x = 2 + y
Equating in equation 1,
Using substitution method,
2(2+ y) + y = 4
4 + 2y + y = 4
3y = 0
y = 0
x = 2 + y
x = 2+ 0
x = 2
Value of x is 2 and y is 0 of the equations 2x + y = 4 and x - y = 2.

Solving by finding the temperature difference,
Option B.
Answer:
4 root 5
Step-by-step explanation:
assume / to be root sign
/10 x /8
simply both roots so that one of numbers is a square number
/10= /2 x /5
/8= /2 x /4
so
/4=2 and /2 x /2= 2
2×2=4 and you have /5 left over so
4/5
hope this helps!
