Step-by-step explanation:
A polynomial in standard form begins with the term with the largest exponent and the remaining terms in descending order of exponents.
given
15
- 6x + 13x² - 1 ←
is largest exponent, hence
15
+ 13x² - 6x - 1 ← in standard form
Answer:
x= 2
x= -3
Step-by-step explanation:
<u>Solving as normal quadratic equation:</u>
- 2x^2+2x=12
- x^2 +x = 6
- x^2 + x - 6= 0
- x = (-1 ± √(1+4*1*6)/2
- x = ( - 1 ± √25)/2
- x = (-1 ± 5)/2
- x= 2
- x= -3
<u>Roots are</u> 2 and -3
