2(2x-11)(3x+5)
-0.2x2+12x+11 = 0 Using the quadratic equation formula will give you two solutions which are: x = 30 + the square root of 955 = 60.90307428 to 8 decimal places. or: x = 30 - the square root of 955 = -0.90307428 to 8 decimal places.
When the sum of a number plus 3 is squared, it is 11 more than the sum of the number plus 2 when squared.
11 x 11 is 121.
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
12x = x + 3 11x = 3 x = 3/11

x=5/2*sqr(3)
It is: 3x2+6x-11 = 0
Add 9x to each side: 12x + 11 = -25Subtract 11 from each side: 12x = -36Divide each side by 12: x = -3
x works out as 5/3
11
They intersect at the point of: (-3/2, 11/4)
Negative 11
(x - 1)(x - 11) x = 1,11
The number that equals 121 when squared is 11.
