Question

Hi friends i want 5 question answer please solve it fast
$5 {x}^{2} - 20xy$
$18 {a}^{2}b - 24abc$
$27x {}^{3} y ^{3} - 45x ^{4} y ^{2}$
$5 a(b + c) - 7b(b + c)$
$2x(p ^{2} + q ^{2} ) + 4y(p ^{2} + q ^{2} )$

​

Answer 1

Answer:

Step-by-step explanation:

5x² - 20xy

Take 5x coomon

5x(x - 4y)

18a²b - 24abc

Take 6ab common

6ab(3a - 4c)

27x³y³ - 45x⁴y²

Take 9x³y² common

9x³y² (3y - 5x)

5a(b + c)  - 7b(b+c)

=(5a - 7b)(b + c)

2x(p² + q²) + 4y(p² + q²)

=(2x + 4y)(p² + q²)
