Answer:1.50
Step-by-step explanation:0.50+1.00
Answer:
x 2 +(29/10)x-(21/10) = 0 Add 21/10 to both side of the equation : x 2 +(29/10)x = 21/10 Now the clever bit: Take the coefficient of x , which is 29/10 , divide by two, giving 29/20 , and finally square it giving 841/400 Add 841/400 to both sides of the equation
Step-by-step explanation:
ANSWER

EXPLANATION
The first polynomial is

The second polynomial is

If we add the two polynomials we obtain,

Next we group like terms to obtain,

We simplify the to obtain,

This is the sum of the two polynomials in descending powers of

Descending means from the highest power to the least.
