discriminant= b^2-4ac= (-2)^2-4(4)(9)= -140<0
since discriminant <0, graph is always positive, x has no real roots

Vs<vu
cause smaller sides have smaller angels in front ofthem
Answer:
x = -8
Step-by-step explanation:
Given: 5(x+4)+52=-4x
Distributive Property: 5x+20+52=-4x
Combine like terms: 5x+72=-4x
Subtract 5x on both sides: 72=-9x
Divide both sides by -9: -8=x
Flip the equation around: x=-8
Therefore, x=-8
