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)

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

can you complete your sentence? i could !
