I’m pretty sure it’s c , sorry if it’s wrong tho
quadratic formula:
x = <u>-b ± √(b² - 4ac)</u>
2a
7x² - x = 7
subtract 7 from both sides:
7x² - x - 7 = 0
plug values into the quadratic formula:
x = <u>-(-1) ± √((-1)²- 4(7)(-7))</u>
2(7)
simplify:
x = <u>1 ± √(197)</u>
14
Answer:
0
Step-by-step explanation:
when they have the same variable you can add them together. When adding 10x and --10x, the cancel out (negate) and you are left with 0
