3. what is the solution of 2x2 + 7x + 9 = 0 using quadratic formulapls help me po.
a=2, b=7, c=9
2x²+7x+9=0
Step 1: Use quadratic formula with a=2, b=7, c=9.
x= -b±√b2−4ac /2a
x= −(7)±√(7)2−4(2)(9) /2(2)
x= −7±√−23 /4
No real solutions / Imaginary

14. find the solution of the quadratic equation using the quadratic formula. 2x2+7x=-9
Answer:
x=−1,9/2
Step-by-step explanation:
change it to standard form
2x²+7x+9=0
factor by grouping
(x+1)(2x−9)=0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0
x+1=0
2x−9=0
Set the first factor equal to 0 and solve
x=−1
Set the next factor equal to 0 and solve
x=9/2
