If α and β are the zeroes of the polynomial ax^2 + bx + c, find the value of α^2 + β^2

Pie

Answer:

Step-by-step explanation:

α + β = -b/a

αβ = c/a

α² + β² = (α + β)² - 2αβ

$= (\frac{-b}{a})^{2}-2\frac{c}{a}\\\\= \frac{b^{2}}{a^{2}}-\frac{2c}{a}\\\\=\frac{b^{2}}{a^{2}}-\frac{2c*a}{a*a}\\\\=\frac{b^{2}-2ca}{a^{2}}$

4. Miguel is helping his mom paint his home. He finished 2 rooms in ⅓ of an hour. How many rooms can he paint in 1 hour?

lilavasa [31]

Answer: 6

Step-by-step explanation:

Let's use a rule of three here.

2 rooms in 1/3 h

x rooms in 1 h

$\frac{2}{x}=\frac{\frac{1}{3} }{1}$

Solve for x;

$x=\frac{2*1}{\frac{1}{3} }$

Remember that when you divide by a fraction, you invert the fraction and multiply by the numerator.

1/3 inverted is 3/1 or 3

$x=(2*1)*3$

$x=(2)*3\\x=6$
