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

$49x^{2}-100 = 0$

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

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

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

$7x=-10, 7x=10$

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

Find the discriminant and the number of real roots for this equation.<br> x2 + 2x + 7 = 0

zavuch27 [327]

Answer:

Discriminant = -24

No real roots.

Step-by-step explanation:

x^2 + 2x + 7 = 0

The discriminant = b^2 - 4ac

= 2^2 - 4*1*7

= -24

So there are no real roots.
