Which quadratic equation is equivalent to (x + 2)2 + 5(x + 2) – 6 = 0?

Darya [45]

Quadratic is in the form
ax^2+bx+c=0

so distribute and stuff and simplify
remember
a(b+c)=ab+ac

(x+2)^2+5(x+2)-6=0
remember order of opertaions
(x+2)(x+2)+5(x+2)-6=0
x^2+4x+4+5x+10-6=0
add like terms
x^2+9x+8=0

PLS ANSWER: What is the monomial if a cube of a monomial is: 1/8 a^27

Katarina [22]

Answer:

$\frac{a^{9} }{2}$

Step-by-step explanation:

A monomial is a type of polynomial that has only one term and when there are two terms in the polynomial then it is called binomial.

Say for example (ax) is a monomial and (ax + b) is a binomial.

In our case the cube of a monomial is $\frac{a^{27} }{8}$

Therefore, the monomial will be $\sqrt[3]{\frac{a^{27} }{8}} =\frac{a^{9} }{2}$ (Answer)
