Question
Find the roots
y1=127−2833,y2=127+2833
Alternative Form
y1≈−3.852161,y2≈5.018828
Evaluate
6y2−7y−116
To find the roots of the expression,set the expression equal to 0
6y2−7y−116=0
Substitute a=6,b=−7 and c=−116 into the quadratic formula y=2a−b±b2−4ac
y=2×67±(−7)2−4×6(−116)
Simplify the expression
y=127±(−7)2−4×6(−116)
