    1.x=-9, x=-1

    2.x=-7, x=-5

    3.x=-7, x=2

    4.x=6, x=-2

    5.x²+7x-4=0

    Step-by-step explanation:

    1.x²+10x+9=0

    (x+9)(x+1)=0

    x+9=0 x+1=0

    x=-9. x=-1

    2.x²+12x+35=0

    (x+7)(x+5)

    x+7=0. x+5=0

    x=-7. x=-5

    3. x²+5x-14=0

    (x+7)(x-2)=0

    x+7=0. x-2=0

    x=-7. x=2

    4. x²-4x+12=0

    (x-6)(x+2)=0

    x-6=0. x+2=0

    x=6. x=-2

    5. x²+7x=4

    x²+7x-4=0

    1) x=-1, x=-9

    2) x=5, x=7

    3) x=x=-(7+√65)/2

    4)

    substitute it to its formula
