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
