Factor the trinomial and enter your answer below Write each factor as a polynomial in descending orderx2 plus 7x plus 10?
The idea is to write the factors as follows: (x + ...) (x + ...) (since all terms are positive in this case), then look for numbers that, when added, give 7, and when multiplied, give 10. Possible factor combinations of 10 are 1x10, and 2x5. The only pair of factors that works (that adds up to 7) is 2 and 5.
What is da answer for y 2x5?
10y
What is 2x 5 9?
2x5=9
-2x 5 -4x 7?
I assume that the question means 4x-7=2x+5. In that case, the answer x would equal 6.
How do you multiply powers with the same exponent?
You multiply the bases, for example, 23 x 53 = 103.The general rule is for real numbers ( but it works for others as well) a and b(ab)n =an bnI think it helps to see why this is true. Look at the example given23 is 2x2x253 is 5x5x5If we multiply these we have2x2x2x5x5x5 which is three 2's and three 5's.Now rearrange them which we can do because of the commutative property ofmultiplication and pair up each 2 with a 5 and here is what you have:(2x5)(2x5)(2x5)this is (2x5)3
