2018年3月3日 · x=2 First, get x on a side by itself. To do this, divide both sides by 5. (x/5)/5 = 10/5 This cancels out the 5's on the left side, leaving you with x =10/5.

How do you add #4.5 x 10^4# and #3.0 x 10^5#? How do you write 153200 in scientific notation? How do you multiply #470000000 * .000035# using scientific notation?

2017年6月11日 · x^2-3x+2 N.B the quotient is the answer. If you're unfamiliar with this technique, all you are really doing is choosing a number (can contain a variable, e.g x which you multiply by divisor, (x-5), so that you get an output that is equal to the first term of your polynomial, in this case x^3. For this method you want to work left to right, so the first thing I want to remove is …

2014年11月5日 · |x-5|=10 by removing the absolute value sign, => {(x-5=-10),(x-5=10):} by adding 5, => {(x=-5),(x=15):} Hence, the solutions are x=-5,15. I hope that this was helpful.

2017年8月10日 · (x^2+7x+10)/(x+5)=x+2 x^2+7x+10 = x^2+5x+2x+10 = x(x+5)+2(x+5) = (x+2)(x+5) Hence (x^2+7x+10)/(x+5) = ((x+2)(x+5))/((x+5)) = x+2

2016年1月10日 · To factor trinomials of the form x^2 + bx + c, find two numbers that multiply to c and that add to b. x^2 - 3x - 10 = (x - 5)(x + 2), since -5 • 2 = -10 and -5 + 2 = -3 So, the proper factoring of your expression would be (x - 5)(x + 2). A few exercises, for practice. At the end, I put a bonus expression where a is greater than 1, so feel free to ask how to factor expressions …

2016年5月13日 · How do you find the missing value to create a perfect square trinomial for #x^2+8x#? How do you solve #k^2-6k+8=0# by completing the square? Can every quadratic be solved by using the completing the square method?
