Answer:

Step-by-step explanation:
Let's start by using distributive multiplication:

So:

Grouping like terms:

Now,
is equal to:

In this sense:

In order to satisfied the equality:

Hence, from (1), let's solve for a:

And from (2), let's solve for b:

Let's verify the result evaluating the values of a and b into the original equation:

As you can see, the values satisfy the equation, therefore, we can conclude they are correct.
X^2+10x+29=0
Quadratic Formula:
−b±√b^2−4(ac)/2a
Substitute the values :
a=1, b=−10, and c=29
into the quadratic formula and solve for
x.
10±√(−10)^2−4•(1•29)/ 2•1
Simplify.
Answer: x=5±2i
