Please explain
-5x(squared)-3x+8
I have to factorise it and I don’t get it. Help please?

Answer = (-x +1) (5x +8)

Step-by-step explanation:

-5x² - 3x + 8

To factorize: we look for two numbers that their sum will give -3 and their product will give = -5 × 8 = -40

The numbers are -8 and 5 (hint: -8 +5 = -3 and -8 × 5 = -40)

-5x² - 8x + 5x + 8

-x(5x + 8) +1(5x +8)

(-x +1) (5x +8)

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
