<h3>I'll teach you how to solve 8x² = 15 - 14x</h3>
----------------------------------------------------
8x² = 15 - 14x
Add 14x to both sides:
8x^2 +14x =15-14x+14x
Simplify:
8x^2 +14x =15
Subtract 15 from both sides:
8x^2+14x-15 = 15-15
SImplify:
8x^2+14x-15 = 0
Solve with the quadratic formula:
x=
= 3/4
x=
= -5/2
The solutions to the quadratic formula are:
x= 3/4, x=-5/2
Your Answer Is x= 3/4, x=-5/2
plz mark me as brainliest :)
E is really just 10, and +7 means it's a positive exponent. So it is 3.82 x 10 to the power of 17. I can't write exponents on my phone, but this is scientific notation.
