1 answer:

5 0

Hi,
$-2x^3+6x+4=-2(x^3-3x-2)\\
=-2(x^3+x^2-x^2-x-2x-2)\\
=-2(x^2(x+1)-x(x+1)-2(x+1))\\
=-2(x+1)(x^2-x-2)\\
=-2(x+1)(x^2+x-2x-2)\\
=-2(x+1)(x(x+1)-2(x+1))\\

=-2(x-2)(x-1)^2 \\

Step-by-step explanation:

hello :

x²+4x+4 = x²+2(2x)+2²=(x+2)² use identity : (a+b)² = a²+2ab+b²

( x² + 4x + 4) - 9y² = (x+2)²-(3y)² = (x+2-3y) (x+2-3y) use identity :

Ram donated 2/3 of his monthly income to an NGO, working for the education of the girls, spent 1/5th of his salary on purchasing

OleMash [197]

Answer:

Step-by-step explanation:

Let Ram's salary = ₹ x

Money donated to NGO = (2/3) of x

Money spent on food items = (1/5) of x

Other expenses = (1/5) of x

Balance amount = ₹ 9000

$x - (\dfrac{2}{3}x+\dfrac{1}{5}x+\dfrac{1}{15}x) = 9000\\\\\\x - (\dfrac{2*5}{3*5}x+\dfrac{1*3}{5*3}x+\dfrac{1}{15}x)=9000\\\\\\x-\dfrac{10x+3x+1x}{15}=9000\\\\\\x-\dfrac{14}{15}x=9000\\\\\\\dfrac{15}{15}x-\dfrac{14}{15}x=9000\\\\\\\dfrac{1}{15}x=9000$

x = 9000 * 15

x = ₹ 135000
