Answer 1

Answer: quadratic equaiton is
x= $(-b- √(b^2-4ac) )/(2a)$ or $(-b+ √(b^2-4ac) )/(2a)$

just subsitute and simplify
I will only do one in detail since it takes some time

so first one2b^2+10b+12
a=2
b=10
c=12
subsitute
x= $(-10- √(10^2-4(2)(12)) )/(2(2))$ or
$(-10+ √(10^2-4(2)(12)) )/(2(2))$
pemdas

$(-10- √(10^2-4(2)(12)) )/(2(2))$
do parenthasees or inside exponents
(10^2-4(2)(12) =(100-96)=4
square root of 4=2
(-10-2)/(2 times 2)=-12/4=-3
if -10+square root then
(-10+2)/(2 times 2)=-8/4=-2
answer is
b=-3 or -2

second one
answer is g=-2 or -2/3

3rd
x=-3/2 or 1/2

4th
b= $(5- √(345) )/(16)$ or
$(5+ √(345) )/(16)$

5th
m=-3/2 or 1/3

6th
d=-5/2 or 4/5
