Complete the equation: x2+10x+__=(__)^2 A. 25; x+5 B. 25; x−5 C. 10; x+10 D. 10; x−10
erastovalidia [21]

Answer:

Answer A)  25, and x+5

Step-by-step explanation:

You need to complete the square by adding a constant that makes the quadratic expression a perfect square of a binomial. So base your analysis on the fact that the coefficient accompanying the square term of x is one, and the fact that the middle term has coefficient 10 which is twice "5" so 5 is the likely candidate for the binomial that goes squared: (x + 5) and the square of 5 (25) is what you need to add as constant term to get the perfect square of a binomial:

x^2+10x+25=(x+5)^2

What are the solutions of the equation (x + 2)2 + 12(x + 2) – 14 = 0? Use u substitution and the quadratic formula to solve.
Lisa [10]
(x + 2)²<span> + 12(x + 2) – 14 = 0

</span>(x +2) ² we use the formula (a+b)² = a² + 2ab + b²
<span>
(x</span>² + 2*2*x + 4 ) + (12*x + 12 * 2 ) - 14 = 0
(x² + 4x + 4) + (12x + 24) - 14 = 0
x² + 4x + 4 + 12x + 24 - 14 = 0

<span>we sort expressions
</span>x² + 4x + 12x + 4 + 24 - 14 = 0

<span>reduce
</span>x² + 16x + 14 = 0 

a = 1    b = 16     c=14

Δ = b² - 4ac = 16² - 4*1*14 = 256 - 56 = 200
√Δ = √(2*10*10) = 10√2

x_{1}  =  \frac{-b -  \sqrt{delty} }{2a}  =  \frac{-16 - 10 \sqrt{2} }{2*1}  =  \frac{-8 -5 \sqrt{2} }{1}  = -8 -5 \sqrt{2}

x_{2}  =  \frac{-b +  \sqrt{delty} }{2a}  =  \frac{-16+ 10 \sqrt{5} }{2*1} =  \frac{-8 + 5 \sqrt{2} }{1}  =  -8 + 5 \sqrt{2}

Answer A
