What are the factors of the equation 2x2 plus 10 equals 9x?
2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0
2X2 plus 18X equals 20?
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
How do you factor 2x2 plus 10-9x equals 0?
2x2 + 10 - 9x = 0 or 2x2 - 9x + 10 = 0 So (x - 2)*(2x - 5) = 0
What is X if 2X squared plus 10 equals 100?
If 2x2 + 10 = 100 then: 2x2 = 100 -10 2x2 = 90 x2 = 90/2 x2 = 45 x = 6.708 (to 3 decimal places only)
2x2 plus 6x-8 equals 72?
2x2+6x-8 = 72 2x2+6x-8-72 = 0 2x2+6x-80 = 0 (2x-10)(x+8) = 0
What are the factors of the equation 2x2 plus 10 equals 9x?
2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0
When is 2x2 equals 10?
When counting in base 4, perhaps.
How do you factor 2x2 plus 10-9x equals 0?
