Answer:
[tex] = 1)(2x - 5y {)} \times (2x + 5y)[/tex]
Step-by-step explanation:
[tex]1) {4x}^{2} - 25 {y}^{2} [/tex]
[tex] = {2}^{2} {x}^{2} - 25 {y}^{2} [/tex]
[tex] = {2}^{2} {x}^{2} - {5}^{2} {y}^{2} [/tex]
[tex] = (2 {x)}^{2} - {5}^{2} {y}^{2} [/tex]
[tex] = ( {2x)}^{2} - (5 {y)}^{2} [/tex]
[tex] = (2x - 5y) \times (2x + 5y)[/tex]
[tex]2)4x^{2} - 35 {y}^{2} [/tex]
[tex] = {2}^{2} {x}^{2} - 5y \times 7 {y} [/tex]
[tex] =(2x {)}^{2} - (5y \times 7y)[/tex]
