What is the degree of -5a2b + 4a2 -2b +5
also I need help in finding the product of x + 5 and 3x -2.
also what is the product of -4x2 and x3 + 2x2 -5x + 3....I need the solutions..Thank You for Your help
okay, i know i can't help you with your problem, but I REALLLLLY need help with mine, could you help?
Linear systems, the equations are 4x+3=y and x=y-2
I need the solution, and I'm stuck, PLEASE help me!
Jay10, please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you.
Elissa, first, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.
Substitute y-2 for x in the first equation to solve for y. Put that value in the second equation to solve for x. Check the values by putting both into the first equation.
I hope this helps. Thanks for asking.
To find the degree of a polynomial, you need to determine the highest power of the variable(s) in the expression.
For the expression -5a^2b + 4a^2 - 2b + 5, the highest power of any variable is a^2. Therefore, the degree of the polynomial is 2.
To find the product of (x + 5) and (3x - 2), you can use the distributive property. Multiply each term in the first equation with each term in the second equation, and then combine like terms, if any.
(x + 5) * (3x - 2) = x * 3x + x * (-2) + 5 * 3x + 5 * (-2)
= 3x^2 - 2x + 15x - 10
= 3x^2 + 13x - 10
So, the product of (x + 5) and (3x - 2) is 3x^2 + 13x - 10.
To find the product of -4x^2 and x^3 + 2x^2 - 5x + 3, you again use the distributive property. Multiply each term in -4x^2 with each term in the second expression, and then combine like terms.
-4x^2 * (x^3 + 2x^2 - 5x + 3) = -4x^2 * x^3 + (-4x^2) * 2x^2 + (-4x^2) * (-5x) + (-4x^2) * 3
= -4x^5 - 8x^4 + 20x^3 - 12x^2
So, the product of -4x^2 and x^3 + 2x^2 - 5x + 3 is -4x^5 - 8x^4 + 20x^3 - 12x^2.
