Answer:

The quotient = 2x - 1 and the remainder = 4x + 2

Step-by-step explanation:

$\frac{2x^{3}+5x^{2}-7x+6}{x^{2}+3x-4}=2x+\frac{-x^{2}+x+6}{x^{2}+3x-4}$

$\frac{-x^{2}+x+6 }{x^{2}+3x-4}=-1+\frac{4x+2}{x^{2}+3x-4}$

The quotient = 2x - 1 and the remainder = 4x + 2

IF S.P. = Rs 1,869, loss percent = 11% find C.P.

Veseljchak [2.6K]

Here,

Selling Price (S.P) = Rs 1869

Loss = 11%

Cost Price (C.P) = ?

Let, C.P be x

Now,

Sp = Cp - loss% of Cp

1869 = x - 11/100*x

1869 = (100x - 11x)/100

186900 = 89x

◆ x = Rs 2100

Cp = Rs 2100

I hope you understand...

It's a Right answer...

Thanks♥♥

Multiply the given polynomials. Answers should be simplified and written in standard form.

e-lub [12.9K]

Answer:

a² - 5a - 36

Step-by-step explanation:

(a - 9)(a + 4)

each term in the second factor is multiplied by each term in the first factor, that is

a(a + 4) - 9(a + 4) ← distribute parenthesis

= a² + 4a - 9a - 36 ← collect like terms

= a² - 5a - 36
