x2 + 18x = x(x + 18) which cannot be simplified further.
That factors to (x - 3)(x + 6)
2(x - 3)(x - 3)
x[x+1] squared Simplified is, to my knowledge, x squared plus ( x + 1) squared
(x, y) = (-3, -3) or (3, 3)
(a + x^2)(b + y^2)
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
(x2 + 7x - 18) = (x + 9)(x - 2)
That factors to (x - 3)(x + 6)
12 squared plus 18 squared is equal to 468.
If that's -18y2, the answer is (3x - 2y)(x + 9y)
2(x - 3)(x - 3)
x[x+1] squared Simplified is, to my knowledge, x squared plus ( x + 1) squared
(x, y) = (-3, -3) or (3, 3)
This is the common form of the Pythagorean Theorem. It describes the relationship between the two legs of a right triangle and the hypotenuse.
(a + x^2)(b + y^2)
(x+y)2
X2 + 3X - 18 Ask yourself, what two factors of - 18 add to 3? (X + 6)(X - 3) -----------------
