Question

what is the solution of the quadratic equation 2× _7×+6=0?
​

Answer 1

Answer:

Step-by-step explanation:

2x²+7x+6=0

by mid term splitting

we get 2x²+4x+3x+6=0

          2x(x+2) +3(x+2)=0

          (2x+2)(x+2)=0

therefore 2x+2=0        or        x+2=0

∴x can be -1,-2

Answer 2

Answer:

The QUADRATIC EQUATIONS is :

X= -b- √b²-4ac/2a

The coefficient for a =1, b= -7 and c= -6 substitute these values into the QUADRATIC EQUATIONS:

X

= - (-7) + √ (-7)²-4•1• (-4) / 2•1

X

= (-7) - √ (-7)² - 4•1• (-4) / 2•1

SOLUTION:

X= 7.53

X= 0.53
