4(h2 - 14)
x = -2/3,7/6
You look for a common factor between the two terms, take it out, and use the distributive property.
(x - 2)(2x + 7)
(y - 2)(y - 7)

10+12x=-14 -14-10=12x 12x=-24 x=-2
It is: (x-2)(x-7) when factored
(x - 2)(2x + 7)
(y - 2)(y - 7)
I assume you mean the equation 2x2 + 12x - 10 = 0. Divide by 2: x2 + 6x - 5 = 0 To complete the square, the constant part (the part with no variable) must be half the linear part (1/2 of 6), squared, so in this case you add 14 to each side: x2 + 6x +9 = 14 This can be factored: (x+3)2 = 14 Now, just take the square root of each side: x + 3 = (plus-or-minus) 14 Solve the resulting two equations (one for plus, one for minus).
2(x - 7)(x - 1)
( x - 14 ) ( x + 14 )
x2 - 14 = 51 so x2 = 65 and then x = +/- sqrt(65) = +/- 8.06
12x - 14 = 5x12x = 5x + 147x = 14x = 2
