9
x2 + 8x - 9 = (x + 9)(x - 1)
The factors of 6x2+7x-5 are (3x+5) and (2x-1).
2(5x + 7)(x - 5)
With the help of the quadratic equation formula
It is a quadratic expression
The only factors of 6 which add to 7 are 1 & 6 so: (x - 1)(x - 6)
Using the quadratic formula you get z≅4.91547594742265 or z≅-0.91547594742265
Without knowing the plus or minus values of the given terms then it can't be considered to be a quadratic expression.
There are no rational factors.
midpoint: (x1+x2/2 , y1+y2/2) quadratic: -b plus or minus square root b squared minus 4ac divided by 2a
It is, as stated, 2x2 + x - 1 = 0. That is the quadratic form.
It is a quadratic equation and its solutions are: x = -3/2 and x = 3
