Answer:
-5x
Step-by-step explanation:
Answer:
(2x-5)(3x-2)
Step-by-step explanation:
1)When factoring quadratic equations in for ax²+bx+c you need to separate the b term in a way that the two addends you separate it by should equal a•c. Just do trial and error. In this case you should get -4 and -15. Your separated equation should be:
6x²-4x-15x+10
2)now factor out a common factor from the first two terms and one from the last two terms you should have:
2x(3x-2)-5(3x-2)
3)finally rewrite this equation into two separate factors and you have your answer.
Answer:
x=18√2 or x=−18√2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
9/8x^2=729
Step 2: Divide both sides by 9/8.
9/8x^2/9/8=729/9/8
x^2=648
Step 3: Take square root.
x=±√648
x=18√2 or x=−18√2
I believe not, has to be more than 90° and less than 180°.
