(2x+3)(x+3)
(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
It is impossible but if it were x squared plus 2x minus 15 the equation would be (x+5) (x-3) with x being equal to either -5 or 3. If the original problem was x squared minus 2x minus 15 the equation would be (x-5)(x+3) and x would be equal to either 5 or -3
2(x + 3)(x + 1)
x2 + x2 = 2x2 2x^2
2x2 + x2 = 3x2
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
This expression factors as x -1 quantity squared.
Numerator = (x + 4)*(x + 3) Denominator = (2x - 1)*(x + 3) Calcelling out the common factor, (x + 3), the answer is (x + 4) divided by (2x - 1) provided x ≠0.5
(-2x2 + x + 1) / (x - 1) = (-2x - 1)(x - 1)/(x - 1) = -2x - 1
-x2+2x

It is: 4x squared
2x2 + 2x = 2x(x+1)
if you want to factorise it then it will become (2x + 5)(x + 2) if it was equal to something then you would work it out differently. hope this helps
