Answer:
-(x + 1)(7x - 12)
Step-by-step explanation:
Step 1: Factor out a -1
-1(7x² - 5x - 12)
Step 2:
Think. Answer this question: "What 2 numbers multiply up to -12 and adds up to -5 while 7 is an x coefficient?". You answer should be -12 and 1.
So, <em>factor</em>.
-1(x + 1)(7x - 12)
To double check, just expand/FOIL everything and see if it is the same as the original expression.
I'm pretty sure it's no...
Answer:
C. x =(1±i√11)/3
Step-by-step explanation:
Use the quadratic formula to find the solutions.
(−b±√b²−4(ac))/2a
Substitute the values a=3, b=−2, and c=4 into the quadratic formula and solve for x.
2±√(−2)²−4⋅(3⋅4)2⋅3
Simplify.
x=(1±i√11)3
