Question

It's math please help​

Answer 1

a)

2x2+6x+1=0

For this equation: a=2, b=6, c=1

2x2+6x+1=0

Step 1: Use quadratic formula with a=2, b=6, c=1.

x=−b±√b2−4ac2a

x=−(6)±√(6)2−4(2)(1)2(2)

x=−6±√284

x=−32+12√7 or x=−32+−12√7

Answer:

x= −32+12√7  or  x= −32+−12√7

b)

3x2−7x−2=0

For this equation: a=3, b=-7, c=-2

3x2+−7x+−2=0

Step 1: Use quadratic formula with a=3, b=-7, c=-2.

x=−b±√b2−4ac2a

x=−(−7)±√(−7)2−4(3)(−2)2(3)

x=7±√736

x=76+16√73 or x=76+−16√73

Answer:

x= 76+16√73  or  x= 76+−16√73
