Answer:
-5x² -4x +8
Step-by-step explanation:
Eliminate parentheses and collect terms.
(-2x² +3) -(3x² +4x -5)
= -2x² +3 -3x² -4x +5
= (-2-3)x² -4x +(3 +5)
= -5x² -4x +8
Answer:
1\times 28=28\\2\times 14=28\\4\times 7=28
Step-by-step explanation: To obtain number 28, we will find the factors of this number.
Factors of this number are: 1, 2, 4, 7, 14, 28
From the given factors, we can find the combinations which will givs us the product as 28
We are asked to find the multiplication ( times) of two number that will yield a number 28. So, the combinations will be
1\times 28=28\\2\times 14=28\\4\times 7=28
