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)

step-by-step explanation:

if x = 2 you have to find x to finish the problem

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
