Write the given trinomial if possible as a square of a binomial or as an expression opposite to a square of a binomial:

Ksenya-84 [330]

$\frac{4}{9}b^2 + 0.4bc + 0.09c^2 = \frac{4}{9}b^2 + \frac{4}{10}bc + \frac{9}{100}c^2 = (\frac{2}{3}b + \frac{3}{10}c)^2$

Determine the value of a if one solution to the quadratic equation is x equals 5 + 3/2 I

Sindrei [870]

The value of a is $\frac{-9}{4}$

Step-by-step explanation:

<u>1. Determine the other solution of x</u>

If one value is 5 + $\frac{3}{2}$ then the other value is 5 - $\frac{3}{2}$

<u>2. Use reverse technique to find the equation</u>

(5 + $\frac{3}{2}$ ) (5 - $\frac{3}{2}$ ) = 0

25 - $\frac{-15}{2}$ + $\frac{15}{2}$ - $\frac{9x^{2} }{4}$ = 0

- $\frac{9x^{2} }{4}$ + 25 = 0

<u>3. The equation is</u> - $\frac{9x^{2} }{4}$ + 25 = 0

<u>4. Find the value of a</u>

a is the number with the variable $x^{2}$ therefore it is - $\frac{9}{4}$
