The expression 2x⁴ + 5x³ - 8x - 20 can be express as follows;
x³(2x + 5) - 4(2x + 5)
<h3>How to factorise an expression?</h3>
2x⁴ + 5x³ - 8x - 20
Therefore,
2x⁴ + 5x³ - 8x - 20
x³(2x + 5) - 4(2x + 5)
Hence, the expression 2x⁴ + 5x³ - 8x - 20 can be express as follows:
2x⁴ + 5x³ - 8x - 20 = x³(2x + 5) - 4(2x + 5)

Answer:
you can use the quadratic formula to get theses:-
x =[-8 +/- sqrt(8^2 - 4*2*-3)] / 4
= -2 +/- sqrt88) / 4
= 0.35, -4.35 to nearest hundredth
Step-by-step explanation:
She has 160 books , you multiply the number of boxes times how many are in each box. 5x32= 160
<span>Find the relationship of 1’s in the given number.
given number = 911 147 835
before we are going to determine the relationship of 1’s , let’s give each
digit’s place value.
9 hundred million
1 ten million
1 million
1 hundred thousand
4 ten thousands
7 thousands
8 hundreds
3 – tens
5 - ones
Now, we have the 1 ten million, 1 million, and 1 hundred thousand
What is the relationship of the 3.
=> we’ll those 1’s are 10 times greater with each other
=> 1 million is 10 times greater than 1 hundred thousands
=> 100 000 x 10 = 1 000 000
=> 1 ten million is ten times greater than 1 million
=> 1 000 000 x 10 = 10 000 000</span>
The other answers confuse me. 267.5 since 3.5=0.035 so 250x0.03.5=8.75x2=17.5+250
