I) show that y1(x) = x2 is a solution of the equation xy" - 2y = 0. ii) find a second solution ya(w) using the method of reduction of order. iii) does the set {91(x), y2(2)} form a fundamental set of solutions for the homogeneous equation in part i)? if so, write the general solution of the equation.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
