    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:

    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
