Does this equation have two real solutions 7x2 -8x -6 equals 0?
yes
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
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 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
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
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
