A décima consists of 44 lines, each of which generally has eight syllables. A décima consists of one stanza of fourlines, and four more stanzas of ten lines each. Each of the four lines of the first stanza is repeated later in the poem. Sometimes when these lines are repeated, they are slightly altered.
Answer:
-3, 5/2
Step-by-step explanation:
What are the roots of the function y = 4x2 + 2x – 30?
To find the roots of the function, set y = 0. The equation is 0 = 4x2 + 2x – 30.
Factor out the GCF of : 2, so the equation becomes 0 = 2(2x2+x-15)
Next, factor the trinomial completely. The equation becomes: 0=2(x+3)(2x-5)
Use the zero product property and set each factor equal to zero and solve.
x+3=0 2x-5 = 0
x = -3, 5/2
The roots of the function are -3, 5/2.
Hope this helped!
2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
