Solve the equation for all values of x.<br> (8x+9)(49x^2-100)=0
Liono4ka [1.6K]

Answer:

x = \frac{-9}{8} , \frac{-10}{7} , \frac{10}{7}

Step-by-step explanation:

8x+9=0

8x=-9

x = \frac{-9}{8}

or

49x^{2}-100 = 0

(7x)^{2} -10^{2} =0,

(7x+10)(7x-10)=0

7x+10=0, 7x-10=0

7x=-10, 7x=10

x=-\frac{-10}{7}, x = \frac{10}{7}

Help me find like terms, (multiple choice).
vichka [17]

Answer:

Like terms:

\frac{1}{2}x^{2}

1.25x²

-8x²

Step-by-step explanation:

Like terms are terms that have the same variable to the same exponent.  In this case, the only like terms are those with the variable 'x' to the exponent of '2', or x².  This would include the terms:

\frac{1}{2}x^{2}

1.25x²

-8x²

The term 5yx², also includes x², however, it also includes the variable 'y' which makes it 'unlike' the other terms.
