It is 3 - 14x
negative 16
8
-7 -(+7) = -7 -7 = -14
8.49*10 - 7 = 77.9
3/4w+8=1/3-712(3/4w+8)=12(1/3w-7)9w+96=4w-849w-4w+96=4w-4w-845w+96=-845w+96-96=-84-965w=-1805w/5=-180/5w=-36
x2 + 2x - 7 is a quadratic polynomial. Every polynomial defines a function called P. Any value of x for which P(x) = 0 is a root of the equation and a zero of the function. x2 + 2x - 7 = 0 add 1 and 7 to both sides x2 + 2x + 1 = 8 (x + 1)2 = 8 take the square root of both sides x + 1 = ± √8 subtract 1 to both sides x = -1 ± 2√2 Thus, the roots of the equation are -1 - 2√2 and -1 + 2√2.
