have the teachers taken today off????
geez - impatient much?
I shall assume you mean
2x^2 - 11x = -12
2x^2 - 11x + 12 = 0
(2x-3)(x-4) = 0
x = 3/2 or 4
I shall assume you mean
2x^2 - 11x = -12
2x^2 - 11x + 12 = 0
(2x-3)(x-4) = 0
x = 3/2 or 4
Even teachers have their own lives, you know! Please be patient because they aren't robots!
2x^2 - 11x + 12 = 0
A*C = 2*12 = 24 = -3*-8. sum = -11 = B.
2x^2 - (3x+8x) + 12 = 0
x*(2x-3) -4(2x-3) = 0
(2x-3)(x-4) = 0
2x-3 = 0, X = 3/2.
x-4 = 0, X = 4.
A*C = 2*12 = 24 = -3*-8. sum = -11 = B.
2x^2 - (3x+8x) + 12 = 0
x*(2x-3) -4(2x-3) = 0
(2x-3)(x-4) = 0
2x-3 = 0, X = 3/2.
x-4 = 0, X = 4.
