Select the quadratic equation that has no real solution. o + 2x2 +6x-20 = 0 2x2 + 20x+6=0 o 2x2 + 20%-6=0 2x2 + 6x + 20 = 0​

18a

step-by-step explanation:

simply because it is. it's the highest common factor

y=mx+

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
