A = (2x + 4)(x^2 - 2)
A = 2x(x^2) + 2x(-2) + 4(x^2) + 4(-2)
A = 2x^3 + -4x + 4x^2 + -8
A = 2x^3 + 4x^2 - 4x - 8
Hope this helps!! :)
Answer:
3/4
Step-by-step explanation:
to add fractions you have to let them have the same denominator or bottom number
so to make 3 and 12 the same number you would multiply 3 by 4
when multiplying the bottom number of a fraction by 4 you multiply the top too
so 2/3 becomes 8/12
then you can add
1/12 + 8/12 is 9/12
at the end you can simplify 9/12 into 3/4 by dividing the equation by 3/3 or both the top and bottom by 3
<span>the equation -2x² + 5x -3=0, we notice that the sum of the coefficient equals 0, -2+5-3=0, if such a case happens, the solution of the previous equation will be, x=1 (always) and x= c/a, a=-2, and c=-3, so x=-3/-2, finally, the answer is: the 2 in the denominator should be -2</span>
