What is 40b squared c squared divide 5bc?
40b squared c squared divide 5bc = 8
What is one important difference between solving equations and solving inequalities?
One important difference between solving equations and solving inequalities is that when you multiply or divide by a negative number, then the direction of the inequality must be reversed, i.e. "less than" becomes "greater than", and "less than or equal to" becomes "greater than or equal to".Actually, from a purist's sense, the reversal rule also applies with equations. Its just that the reversal of "equals" is still "equals". The same goes for "not equal to".
What is the similarities of solving equations and inequalities?
You solve an inequality in exactly the same was as you solve an equation, by doing the same thing to both sides. The only difference is if you multiply/divide by a negative number, when you have to turn the inequality around.
Why does the quadratic formula work every time for quadratic equations?
The quadratic formula works for every quadratic equation because it is the standard form of a quadratic solved for x. ax2+bx+c=0 - Standard Form, how quadratic equations are normally displayed x2+bx/a+c/a=0 - Divide both sides by a, Division Property of = x2+(b/a)x= -(c/a) - Separate variables and constants, Subtraction Property of = x2+(b/a)x+(b/2a)2=(b/2a)2-(c/a) - Complete the square. (b/2)2 (x+b/2a)2=(b2-4ac)/4a2 - Factor and Simplify x+b/2a=+/-sqrt((b2-4ac)/4a2) - Square Root both sides. x=-(b/2a)+/-sqrt(b2-4ac)/2a - Solve for x, Subtraction Property of = x=(-b+/-sqrt(b2-4ac))/2a - The Quadratic Equation, Simplify
Is it good to divide the equation 2x squared 8x 6 by two to factorise such equation?
If you mean the quadratic expression: 2x2+8x+6 then dividing all terms by 2 it becomes x2+4x+3 which is (x+1)(x+3) when factored
How do you solve the equation y equals x squared?
If you are solving for y, it is fine. If you are solving for x, divide both sides by x and the equation should be x = y/x
How do you solve 5r squared equals 80 with the Quadratic Formula?
You don't need to use the quadratic formula because:- 5r2 = 80 Divide both sides by 5: x2 = 16 Square root both sides: r = 4
What is 40b squared c squared divide 5bc?
40b squared c squared divide 5bc = 8
What are the steps in solving exponential equations?
multiply= you add the exponets together and keep the same base divide= you subtract the exponet and keep the base the same

Cm squared to meters squared?
divide by 100 and then divide by 100 again or divide by 10,000 - same thing
How do you convert inches squared into feet squared?
divide by 144
If 720 inches squared is how many feet squared?
Divide that by 144 (12 squared).
What is the answer to 4m²- 40m plus 56 equals 0?
-24m = 56Improved answer:First divide all terms by 4 and then solve this quadratic equation by completing the square which will have two solutions:m2-10+14 = 0(m-5)2+14 = 0(m-5)2+14-25 = 0(m-5)2 = 11m-5 = + or - the square root of 11m = 5 + or 5 - the square root of 11Alternatively you can solve this equation by using the quadratic equation formula which will give you the same answer.Your tutor should be familiar with the above methods of solving quadratic equations if you aren't too sure.
Explain how solving inequalities is alike and different from solving equations?
Most of the steps are the same. The main difference is that if you multiply or divide both sides of an inequality by a NEGATIVE number, you must change the direction of the inequality sign (for example, change "less than" to "greater than").
Convert cm2 to inch squared?
Divide by 6.4516 divide by 6.4515
What is the similarities of solving equations and inequalities?
