Question

1.Add the given polynomials
(x²–2x²-9)+(4x3+x+7.)

2.If P(x) = x3 + 2x2 - 5x + 7 then find p (0).

3.If x is the geometric mean of 25 and 4, then find the value of x.

4.If
$\frac{a}{b} = \frac{5}{2}$
then find the value of the ratio
$\frac{a + 2b}{a - 2b}$

5.Express the recurring decimal 0.888.... in
$\frac{p}{q}$
form



6.Solve
$| \frac{5 - x}{2} |$
​

Answer 1

Answer:

1.) (x²-2x²-9)+(4x³+x+7)=4x³+3x²+x-2
