Does this equation have two real solutions 7x2 -8x -6 equals 0?
yes
Factor x squared - 8x plus 12 equals 0?
(x - 6)(x - 2)
How do you solve 7x2 plus 8x minus 12 equal 0?
Try to factor the left side and set each of the linear expressions equal to zero. 7x^2 +8x -12= 0 (7X-6)(X+2)=0 7X-6=0 X=6/7 X+2=0 X=-2
7x2 plus 3x - 4 equals 0?
(7x - 4)(x + 1 ) making x = either 4/7 or -1 Check: (7 x 16/49) + 12/7 = 16/7 + 12/7 = 4 ok 7 + (-3) = 4 ok...and there you have it.
What are the zeros or x-interecepts or soultions or roots of the quadratic equation -7x2 - 27x plus 28 equals 0?
Using the quadratic equation formula:- x = -4.706950048 and x = 0.849071913
How do you solve the quadratic equation 7x2-5x equals 0 by factoring?
if the x in "7x2" is variable x, then 7x(2)-5x=0 14x-5x=0 9x=0 x=0 if the x in "7x2" is a symbol for multiplication, then 7(2)-5x=0 14-5x=0 -5x= -14 5x=14 x= 14/5 x= 2 4/5 or, to factor it out... x(14-5)=0 x(9)=0 9x=0
Does this equation have two real solutions 7x2 -8x -6 equals 0?
yes
What is 7x2-56x plus 112 equals 0?
7X^2 -56X + 112 = 0 divide through by 7 X^2 - 8X + 16 = 0 factor (X-4)(X-4) X = 4
What is the factor of x2 - x - 12 equals 0?
(x+3)(x-4)
What is 7x to the second power plus -10x plus 3 equals 0 factored?
7x2-10x+3=0 (7x-3)(x-1)=0
What is the factor of x2 plus 7x plus 12 equals 0?
(x + 3)(x + 4)
Factor x squared - 8x plus 12 equals 0?
(x - 6)(x - 2)

7x2 plus 3x - 4 equals 0?
(7x - 4)(x + 1 ) making x = either 4/7 or -1 Check: (7 x 16/49) + 12/7 = 16/7 + 12/7 = 4 ok 7 + (-3) = 4 ok...and there you have it.
What degree polynomial equation is 4x3 plus 7x2 - 4x equals 0?
The "degree" is the highest power - in this case, the 3 in 4x3 (4 times to the third power).
Is 0x3 equals 0 a zero factor law?
Yes.
What is the factor form of -14a-a2 equals 0?
a(-14-a) = 0 so a = 0 or a = -14
