Use the quadratic f(x)=x²+3x-4 and use any method to solve for the Zeros. Use the same function to solve for x when y is 6. F(x)

Katyanochek1 [597]

Answer:

a) $f(x) = (x+4)\cdot (x-3)$ , b) $x = -5$ or $x = 2$ , c) $x \approx 2.531$ or $x \approx -5.531$

Step-by-step explanation:

a) The function is solved by factorization:

$f(x) = (x+4)\cdot (x-3)$

b) The function has the following form:

$x^{2} + 3\cdot x - 4 = 6$

$x^{2} + 3\cdot x - 10 = 0$

The roots of the polynomial are found by factorization:

$(x+5)\cdot (x-2) = 0$

$x = -5$ or $x = 2$

c) The function has the following form:

$x^{2} + 3\cdot x - 4 = 10$

$x^{2} + 3\cdot x - 14 = 0$

The roots of the polynomial are determined by the General Formula for the Second-Order Polynomial:

$x_{1} = \frac{-3+\sqrt{3^{2}-4\cdot (1)\cdot (-14)}}{2\cdot (1)}$

$x_{1} \approx 2.531$

$x_{2} = \frac{-3-\sqrt{3^{2}-4\cdot (1)\cdot (-14)}}{2\cdot (1)}$

$x_{2} \approx -5.531$

Jeff has five less than twice the number of clients that Kenan has. The product of the number of clients they have is 322. Write

HACTEHA [7]

Answer:

The equation that represents this situation is 2c² - 5c - 322 = 0

Step-by-step explanation:

∵ Kenan has c clients

∵ Jeff has five less than twice the number of clients that

Kenan has

- That means multiply c by 2 and then subtract 5 from the

product to find the number of Jeff's clients

∴ Jeff's clients = 2c - 5

∵ The product of the number of clients they have is 322

∴ c × (2c - 5) = 322

- Multiply c by the bracket (2c - 5)

∴ (c)(2c) + (c)(-5) = 322

∴ 2c² + (-5c) = 322

- Remember (+)(-) = (-)

∴ 2c² - 5c = 322

- Subtract 322 from both sides

∴ 2c² - 5c - 322 = 0

The equation that represents this situation is 2c² - 5c - 322 = 0
