Answer 1

Answer:

i.solution:

10x2-18x3+14x4=2x2(7x2-9x+5)

Step-by-step explanation:

10x2-18x3+14x4

2x2(5-9x+7x2)

2x2(7x2+9x+5

7x2-9x+5

ax2+bx+c

d=b2-4ac 7/0

d=(-9)2 -4(7) (5g

= 81 - 35 ✖4

= 81 -140

= - 5a (<0)

ok?

Answer 2

Answer:

Solution :-

1) 10x² - 18x³ + 14x⁴

➞ 14x⁴ - 18x³ + 10x²

➞ 2x²(7x² - 9x + 5)

∴ The answer of this question is 2x²(7x² - 9x + 5)

2) 5x²y + 10xyz + 15xy²

➻ 5xy(x + 2z + 3y)

∴ The answer of this question is 5xy(x + 2z + 3y)

3) p²x² + c²x² - ac² - ap²

➙ c²x² + p²x² - ac² - ap²

➙ x²(c² + p²) - a(c² + p²)

➙ (c² + p²) (x² - a)

∴ The answer of this question is (c² + p²) (x² - a)

4) 15(x + y)² - 5x - 5y

➻ 15(x + y)² - 5(x + y)

➻ 5(x + y) {3(x + y) - 1) [ Taking 5(x + y) common ]

➻ 5(x + y) (3x + 3y - 1)

∴ The answer of this question is 5(x + y) (3x + 3y - 1)
