( x - 2)( x - 6) = 0
x = 2 or x = 6
Two equations: a linear one in y and a quadratic in x.
Yes
X= 1.567764363, -9.567764363
Using the quadratic equation formula:- x = 3.795831523 or x = -5.795831523
They intersect at points (-2/3, 19/9) and (3/2, 5) Solved by combining the two equations together to equal nought and then using the quadratic equation formula to find the values of x and substituting these values into the equations to find the values of y.
Two equations: a linear one in y and a quadratic in x.
It is a quadratic equation and its solutions can be found by using the quadratic equation formula.
Using the quadratic equation formula: x = -5-/+ the square root of 7
X= 1.567764363, -9.567764363
Yes
Using the quadratic equation formula:- x = 3.795831523 or x = -5.795831523
no only equations with x2 and lower powers can be considered quadratic. those with x3 cannot be considered quadratic, just as x2 cannot be considered linear
a=5: c=4
They intersect at points (-2/3, 19/9) and (3/2, 5) Solved by combining the two equations together to equal nought and then using the quadratic equation formula to find the values of x and substituting these values into the equations to find the values of y.
Why are Quadratic equations, which are expressed in the form of ax2 + bx + c = 0, where a does not equal 0,
the answer
Combine the equations together and using the quadratic equation formula it works out that the point of contact is at (5/8, 5/2)
