Question

(5x-3)²= (7x-9)²= (3x+5)² =(11x-1)= (6x-4x) =(5x-1)(3x+5) = (3x-5)(3x+5) = 49x²-16 =36x²-25

Answer 1

(5x-3)²=25х²-30х+9

(7x-9)²=49х²-126х+81

(3x+5)² =9х²+30х+25

(11x-1)²= 121-22х+1

(6x-4x)²36х²-48х+16х² =

(5x-1)(3x+5) = 15х²+(25-3)х-5= 15х²+22х-5

(3x-5)(3x+5) = 9х²-25

49x²-16 =(7х-4)(7х+4)

36x²-25=(6х-5)(6х+5)

Answer 2

It seems like you've provided a list of equations and expressions. Let's break down each one:

1. $(5x-3)^2$: This is a quadratic expression. Expanding it gives $25x^2 - 30x + 9$.

2. $(7x-9)^2$: This is another quadratic expression. Expanding it gives $49x^2 - 126x + 81$.

3. $(3x+5)^2$: Expanding this quadratic expression gives $9x^2 + 30x + 25$.

4. $(11x-1)$: This is a linear expression. It simplifies to $11x - 1$.

5. $(6x-4x)$: This is a subtraction of two linear terms. It simplifies to $2x$.

6. $(5x-1)(3x+5)$: This is a product of two linear expressions. Expanding it gives $15x^2 + 20x - 3x - 5$, which simplifies to $15x^2 + 17x - 5$.

7. $(3x-5)(3x+5)$: This is a difference of squares. Expanding it gives $9x^2 - 25$.

8. $49x^2-16$: This is a quadratic expression.

9. $36x^2-25$: This is another quadratic expression.
