Question

Y=(x-1)3(x+3) help me please guys

Answer 1

Y=(x-1)*3(x+3)
y=(x-3)*(x+3)
y=3x²+9x-3x-9
y=3x²+6x-9
y=3x²+6x-9

Answer 2

У = (3х-3)(х+3)
у = 3х^2+9х-3х-9
у = 3х^2 +6х - 9
D=36+108=144
X1= 1
X2= - 3

Answer 3

Sure, I'd be happy to help you with the expression Y = (x - 1)^3(x + 3).

To simplify this expression, we can use the distributive property and then perform the necessary operations.

Step 1: Expand the expression using the distributive property. Y = (x - 1)^3(x + 3) Y = (x - 1)(x - 1)(x - 1)(x + 3)

Step 2: Multiply the terms together. Y = (x^2 - x - x + 1)(x - 1)(x + 3) Y = (x^2 - 2x + 1)(x^2 + 2x - 3)

Step 3: Multiply again and simplify further. Y = x^2(x^2) + x^2(2x) + x^2(-3) - 2x(x^2) - 2x(2x) - 2x(-3) + 1(x^2) + 1(2x) + 1(-3) Y = x^4 + 2x^3 - 3x^2 - 2x^3 - 4x^2 + 6x + x^2 + 2x - 3 Y = x^4 - 4x^2 + 8x - 3

So, the simplified form of the expression is Y = x^4 - 4x^2 + 8x - 3.
