x = -3 or x = 1/4

Step-by-step explanation:

Please see the graph in the attachment.

4 x^2 + 11 x - 3= 0

4 (x + 3) (x - (1/4)) = 0

(x + 3)= 0 or (x - (1/4))= 0

What are the roots of the quadratic equation x2+2x=-5
stiks02 [169]

Answer:

x = -1 +/-2i

Step-by-step explanation:

Write the equation in standard form to find the roots, also known as the solutions, zeros, or x-intercepts, of the quadratic.

x² + 2x + 5 = 0

Use the quadratic formula by substituting a= 1, b = 2 and c = 5.

x = \frac{-2 +/- \sqrt{(-2)^2 - 4(1)(5)} }{2(1)} = \frac{-2 +/-\sqrt{4 -20 } }{2} = \frac{-2 +/-\sqrt{-16 } }{2} = \frac{-2 +/-4i }{2} = -1 +/-2i

Answer:

\sqrt32

Step-by-step explanation:

You use the Pythagorean theorem since a triangle is formed.

a^{2} +b^{2} =c^{2}

6^{2} = 2^{2} +x^{2}

36-4 =x^{2}

x= \sqrt{32}
